UnZip, version 6.1c, ?? ??? 2016
These changes occurred in beta versions 6.10a through 6.1c.
Features added (or removed):
6.10a00 (05 Jul 2010):
- Copy over UnZip 6.00 and rename as UnZip 6.10a00. [EG]
6.10a01 (05 Jul 2010):
- No feature changes.
6.10a02 (10 Jul 2010):
- Add new command parser code from new-cmdparser/unz6-newcmdparser-diffs.txt,
which is a modified version of the new Zip parser. Some modifications to
account for changes in UnZip since code was written. UnZip now supports
use of get_option() to parse the command line, adding support for a
command table and long options. Command parsing now mostly similar to
that used in Zip, but most of UnZip syntax preserved. One big difference
is inverting an option (making negative) is now done by a trailing "-"
instead of a leading one. See the long help and the manual for the
current syntax of these and all commands. (unzip.c, unzpriv.h, zipinfo.c,
vms/cmdline.c) [EG]
- Changed zipgrep to cope with the new command parser. Added environment
variable ZIPGREP_UNZIP to let the user specify a particular UnZip program
to use. (unix/zipgrep) [SMS]
- Add new option --license to show the license and note added to short help
displayed when no command arguments that this new option exists. Allows
distribution of UnZip under the current Info-ZIP license without additional
documentation. Calls show_license(). (unzip.c) [EG]
- Add preliminary support for AppleDouble storage of resource information on
Mac platforms. (extract.c, fileio.c, globals.h, unzip.c, unzip.h,
unzpriv.h, unix/unix.c) [SMS]
- Add VMS symlink works check. (extract.c) [SMS]
- Add new option --options to show all available options. (unzip.c) [EG]
- Add strerror() if port does not have one. Add check for mbstr.h.
(unzpriv.h, unix/configure, unix/unix.c) [SMS]
- Add uname calls to get system identification. (unix/configure,
unix/unix.c) [SMS]
- Add control of UID/GID and SGID using X_flag and K_flag. (unix/unix.c,
vms/vms.c) [SMS]
- Add verbose report. (vms/cmdline.c, vms/unz_cli.cld) [SMS]
- Update VMS notes. (vms/notes.txt) [SMS]
- VMS return code updates and allow restoring old status codes. (vms/vms.c)
[SMS]
6.10a03 (30 Jul 2010):
- fnfilter() now converts to a wide character string and does the isprint()
check on that, avoiding the issue of doing the check on multi-byte
characters. (extract.c, win32/win32.c, unzpriv.h, process.c) [EG]
- Update TODO list. (ToDo) [EG]
6.10a04 (05 Aug 2010):
- Updated INSTALL with latest information. [SMS]
- Remove 8-bit ASCII characters from ToDo. Add items. [SMS]
- Add ZipInfo "C" option to command table. (unzip.c) [SMS]
- Add new option --commandline to show the processed command line and exit.
Add new function show_commandline(). Update extended help. (unzip.c,
fileio.c, unzip.h, zipinfo.c) [EG]
6.10a05 (08 Aug 2010):
- No feature changes.
6.10a06 (09 Aug 2010):
- Update version information in description file. (file_id.diz) [EG]
6.10a07 (10 Aug 2010):
- Add announcement file. (unzip610a.ann) [EG]
- Replace /[NO]CASE_INSENSITIVE with /CASE_MATCH. (vms/unzip_cli.help,
vms/unz_cli.cld) [SMS]
6.10a (23 Aug 2010):
- Add note to README. Update announcement. (README, unzip610a.ann) [EG]
6.10b01 (12 Sep 2010):
- Restore full Windows Unicode support based on diff in win32-experimental
directory. Mainly involved adding wide character OS calls to Windows
port code. WIN32_WIDE must be defined for the new code to be used, but
this should be the default on Windows platforms from NT on. Currently
Windows 9x Unicode is partially supported, but this support may be pulled
to clean up the code. Some of the new functions include check_for_newerw()
has_win32_wide(), wchar_to_wide_string(), wchar_to_local_string(),
iswildw(), zstat_win32w(), getNTfiletimeW(), defer_dir_attribsw(),
set_direc_attribsw(), FStampIsLocTimeW(), mapnamew(), checkdirw(),
NTQueryVolInfoW(), maskDOSdevicew(), extract_or_test_entrylistw(), and
map2fatw(). (extract.c, fileio.c, process.c, match.c, globals.h, unzip.c,
unzpriv.h, win32/nt.c, win32/nt.h, win32/w32cfg.h, win32/win32.c,
win32/vc6/funzip.dsp, win32/vc6/unzip.dsp, win32/vc6/unzipbz2.dsp,
win32/vc6/unzipsfx.dsp, windll/vc6/dll/unz32dll.dsp) [EG]
6.10b02 (16 Sep 2010):
- Implement -I (--iso-char-set) and -O (--oem-char-set) options to allow user
to set a specific ISO or OEM character set that UnZip should translate
from to create the internal file name strings. Based on the
unzip60-alt-iconv-utf8.patch suggested in a forum thread. This patch is
rather simple, just providing the new options to manually set the input
character set (generally OEM if archive from Windows and ISO otherwise).
These options are currently only available on Unix. This is separate from
the Unicode implementation that allows direct conversion between character
sets and bypasses these new options if an entry has Unicode. These options
are only for converting names from older archives without stored UTF-8 to
names that are readable on a Unix platform. This implementation includes
a short table to automatically guess the code page for a few common
locales. More locales can be added later, and a more complete solution
might be implemented later based on something like the libnatspec or
librcc libraries. However, the goal is for everyone to move to zippers
that support UTF-8 so these options are no longer needed. Enabled by
setting the USE_ICONV_MAPPING macro. Uses the iconv library which must be
available. (unzip.c, zipinfo.c, unix/unix.c, unix/unxcfg.h) [EG]
6.10b03 (06 Nov 2010):
- No feature changes.
6.10b04 (25 Nov 2010):
- Resurrected Acorn port by rewriting/updating the makefiles, replacing
srcrename utility with 32bit compatible BASIC equivalent, replacing APCS-R
swiven.s file with more portable C version, and updating contents & readme
files with compilation instructions for the latest compilers. Fixed a few
compiler warnings/errors and swapped the os_error struct for the standard
_kernel_os_error. (acorn/makefile, acorn/GMakefile, acorn/srcrename,
acorn/acorn.c, acorn/riscos.c, acorn/riscos.h, acorn/swiven.c,
acorn/swiven.h, acorn/Contents, acorn/ReadMe, acorn/RunMe1st updated.
acorn/swiven.s deleted.) [Jeffrey Lee]
- Acorn port: Increased max file name/path length to 1024. (acorn/riscos.h)
[Jeffrey Lee]
- Acorn port: Increased max file name/path length to 1024. (acorn/riscos.h)
[Jeffrey Lee]
- Acorn port: Added SET_DIR_ATTRIB support, so that directories are created
with the right timestamps/attributes. (acorn/riscos.h, acorn/acorn.c)
[Jeffrey Lee]
- Minor edits to Contents. (acorn/Contents) [EG]
- Update VB6 example project to add more comments, change some form object
sizes, and update GUI handling of listing and extracting. Update readme.
(windll/vb/vbreadme.txt, windll/vb/vbunzip.bas, windll/vb/vbunzip.frm,
windll/vb/vbunzip.vbp) [EG]
- Add announcement file for UnZip 6.10b. (unzip610b.ann) [EG]
6.10b05 (29 Nov 2010):
- No feature changes.
6.10b06 (03 Dec 2010):
- Updated INSTALL and README. (INSTALL, README) [EG]

- No feature changes.
6.10b (10 Dec 2010):
- No feature changes.
6.10c01 (15 May 2011):
- Clarify VMS usage line. (unzip.c) [SMS]
- Add compiler test. (unix/configure) [SMS]
- Make -s (spaces to underscores) option generic (unzip.c) [Stan
Sieler]
- Add optional support for AES encryption compatible with WinZip
version (compression method 99). Use Gladman AES implementation.
Note that when the optional AES_WG support is not enabled, this still
changes the old message:
skipping: <name> unsupported compression method 99
to:
skipping: <name> AES_WG encr method not supported
when trying to extract an AES_WG-encrypted file.

- Add AES_WG version to CRYPT_AES_WG line in -v. (unzip.c, unzpriv.h) [SMS]
- Add P6 (search vector) and P7 (macro vector) parameters.
(vms/collect_deps.com) [SMS]
6.10c04 (05 Aug 2011):
- First attempt at support for LZMA compression (method 14). (extract.c,
fileio.c, unzip.c, unzpriv.h, lzma/* (from LZMA SDK), unix/configure,
unix/Makefile, vms/descrip.mms, vms/descrip_deps.mms,
vms/descrip_src.mms) [SMS]
- Create start of zos port. (zos/zcc, zos/zld) [AD]
- Modify handling of non-ASCI file names (-I/-O options) to automatically
guess OEM code page when not already set. Only some common mappings
have been added currently. Only used if USE_ICONV_MAPPING is defined.
(unix/unix.c) [EG, based on patch by Dmitry Butskoy on Red Hat Bugzilla -
Bug 225576]
6.10c05 (13 Aug 2011):
- Add LZMA files needed by UnZip from LZMA SDK version 9.20.
(lzma/7zfile.c, lzma/7zfile.h, lzma/7zversion.h, lzma/alloc.c,
lzma/alloc.h, lzma/lzfind.c, lzma/lzhash.h, lzma/lzmadec.c,
lzma/lzmadec.h, lzma/README_LZMA.txt, lzma/types.h, lzma/orig/lzfind.h)
[SMS]
- Split cmsmvs port into two ports zos and zvm. (cmsmvs/* (removed),
zos/ccunzip.exec, zos/mvs.mki, zos/readme.mvs, zos/unzmvsc.job,
zos/vmmvs.c, zos/vmmvs.h, zvm/install.cms, zvm/mc.exec, zvm/readme.cms,
zvm/unzip.exec, zvm/unzip.makefile, zvm/unzvmc.exec, zvm/vmstat.h,
zvm/whatsnew.cms, zvm/zipinfo.exec) [AD]
- Drop VMS CASE_INSENSITIVE option as conflicts with CASE_MATCH. Add NAMES
option that includes NAMES.LOWERCASE, NAMES.ODS2 (convert names to ODS2),
and NAMES.SPACES (convert spaces to underscores). Add CASE_MATCH = BLIND
(ignore case) or SENSITIVE (don't ignore differences in case).
(vms/cmdline.c, vms/unz_cli.cld, vms/unzip_cli.help) [SMS]
- Add note about self-extracting archives. (vms/install.vms) [SMS]
- Update VMS help for self-extracting archives. (vms/unzipsfx.hlp) [SMS]
6.10c06 (24 Aug 2011):
- Create new Win32 projects for AES_WG and LZMA. Additional cleanup of
the Win32 projects is expected before release. (win32/vc6/unzip.dsp,
win32/vc6/unzip.dsw, win32/vc6/unzipaes.dsp) [EG]
6.10c07 (12 Sep 2011):
- Rename vms/INSTALL.VMS to vms/INSTALL_VMS.txt. Move much of the VMS
material from INSTALL to vms/INSTALL_VMS.txt. Minor update to Mac OS X
to note adding of AppleDouble Finder info and resource fork storage.
(vms/INSTALL_VMS.txt, INSTALL) [SMS]
- Change default to -D everywhere, not only on VMS. Update extended
help. Update man page. (globals.c, unzip.c, man/unzip.1) [SMS]
- Restructure unix build: Restructure, document, reorganize; recognize
IBM compilers (z/OS, z/VM, AIX, Linux. iSeries); recognize z/OS system
(uname -I variant); add $PROD/flags_bz; support build with system zlib,
zlib in tree; support man and doc generation. (unix/configure,
unix/Makefile) [AD]
- Correct z/OS build script options parsing. (zos/zcc, zos/zld) [AD]
- Add z/OS wrapper script for C preprocessor tests. (zos/zccp) [AD]
- For unzip -v, emit IBM compiler OS-specific version. (unix/unix.c) [AD]
- Customize unix build for z/OS UNIX (HAVE_SYS_TIME_H, sys/time.h,
sys/timeb.h, utime.h, et al). (unix/unxcfg.h) [AD]
- Add PORT unix/configure macro, allows reuse by z/OS MVS build (under
z/OS UNIX) (unix/configure) [AD]
- Following changes made to unix/configure, mainly to support z/OS port.
(unix/configure) [AD]
1. A new file $PROD/flags_bz is generated containing just the bzip2
compilation-related flags.
2. UNAME-related flags now in more legible order.
3. For z/OS, use "uname -I" to generate current z/OS information.
4. Now generates installation flags (BINDIR, BINPERMS).
5. Now generates man page flags (MANEXT, MANDIR, MANPERMS);
unix/Makefile supports generic_man and generic_doc.
6. Now generates man page nroff option, currently "-Tascii" or "".
7. Flags renamed for consistency between zip and unzip:
- CFLAGS -> CF
- CFLAGS_BZ -> CF_BZ
- LFLAGS1 -> LF1
- LFLAGS2 -> LF2
8. Flags generated are a superset of zip and unzip and include
additional header checks.
9. OSDEP_xxxx flags contain OS-dependent values:
- OSDEP_C C source files
- OSDEP_H C header files
- OSDEP_S Assembler source files
- OSDEP_OC Object files (C)
- OSDEP_OS Object files (assembler)
These allows multiple OS-dependent C or assembler source files.
10. Use consistent configuration, naming and recipes for assembler
files.
11. Add $PROD/flags values for program extensions:
- PMGEXT Executables
- DLLEXT DLLs (Shared objects)
12. Add $PROD/flags values for RANLIB, RM and LN.
13. Add $PROD/flags values for AR, required by IBM XLC for AIX 64-bit
compiles.
14. Object archive dependencies. Non-blank if library is required:
LIB_AES_WG, LIB_LZMA, LIB_BZ, LIB_Z.
15. ZLIB and BZIP2 support now consistent:
- Supports build within tree via bzip2/Makefile or zlib/Makefile
(if present)
- Supports build with OS-owned libbz2.a (IZ_BZIP2=bzip2, ./bzip2 is
empty)
- Supports build with OS-owned libz.a (IZ_ZLIB=zlib, ./zlib is empty)
- Returns MK_BZ to allow configure to return system-specific BZIP2
makefile name
16. Now supports AF for assembler flags.
17. Support compiler listing options (+ CC on z/OS) for LIST=1.
18. Cleanup targets now same on zip and unzip (clean, clean_bzip2,
clean_exe)
19. All make targets are now explicit for portability; SysV make pattern
matching is not as powerful as gmane or z/OS make (MKS).
20. .SUFFIX reset to prevent builds from using default .c -> .o rules.
21. On z/OS, use CC=c89 (xlc ends with sigkill for failing compiles).
22. On AIX (with IBM XL C) use CC=c89.
23. Use unzip nl_langinfo() test instead of following zip test (which
fails because codeset is not an int).
24. Add test for sys/param.h (for -DNO_PARAM_H).
25. Add test for sys/time.h (separate from entry timing).
26. Add tests for sys/timeb.h and utime.h.
27. Set z/OS linker flag.s
28. Add PORT unix/configure parm, allows reuse by z/OS MVS build (under
z/OS UNIX) [AD]
- Minor updates to -D option help and option descriptions. Add warning
regarding change in option negation (trailing "-" instead of leading).
Add note that split support should be coming by release of UnZip 6.10.
Add mention of automatic code page selection in some cases, but can be
overridden by use of -I and -O. (unzip.c) [EG]
- Additional updates to UnZip man page. (man/unzip.1) [EG]
6.10c08 (22 Nov 2011):
- Add initial implementation of a user-triggered progress message.
Enabled by default, disabled by defining the C macro NO_USER_PROGRESS.
Adds a SIGUSR1 signal handler (non-VMS) or a control-T AST (VMS),
user_progress(). On non-VMS systems, add option -si to display the
UnZip process ID, for convenience in forming a "kill -USR1 <pid>"
command. (unzip.c, unzpriv.h, vms/vms.c) [SMS]
6.10c09 (7 March 2014):
- Added optional support for PPMd compression (method 98). (extract.c,
lzma/Ppmd.h, lzma/Ppmd8.c, lzma/Ppmd8.h, lzma/Ppmd8Dec.c,
lzma/README_LZMA.txt, unix/configure, unix/Makefile,
vms/build_unzip.com, vms/descrip.mms, vms/descrip_deps.mms,
vms/descrip_mkdeps.mms, vms/descrip_src.mms) [SMS]
- Added a PPMd test archive to the kit, "testmake_ppmd.zip", and a new
"make" target, "test_ppmd" to use it. (testmake_ppmd.zip,
unix/Makefile, unix/test_unzip.sh, vms/descrip.mms,
vms/test_unzip.com) [SMS]
- Added recognition (only) of JPEG compression (method 96). (list.c,
unzpriv.h, zipinfo.c) [SMS]
- Added archive name to user-triggered progress message. (unzip.c) [SMS]
- Added data-dependent supplementary info to verbose test (-tv) report
for LZMA- and PPMd-compressed data. (extract.c, man/unzip.1) [SMS]
- Initial attempt to provide a callable-UnZip interface on UNIX and VMS
systems. Specify LIBUNZIP at build time to create libizunzip.a
(Unix) or LIBIZUNZIP.OLB and LIBIZUNZIP.OPT (VMS), which may be
linked with a user-supplied program. Comments in an example main
program source module, libiz/izunzip_example.c, explain some usage
details. (libiz/izunzip_example.c, unix/configure, unix/Makefile,
vms/build_unzip.com, vms/descrip.mms, vms/descrip_deps.mms,
vms/descrip_mkdeps.mms, vms/descrip_src.mms) [SMS]
- Initial attempt to support Windows MinGW environment with UNIX
builders ("generic" target). No DLL. (unix/configure, unix/Makefile)
[SMS]
- Added support for BAE Systems STOP OS, which lacks chown(). The
"configure" script now checks for chmod() and chown(), and unix.c now
honors the resulting NO_CHMOD and NO_CHOWN macros. (unix/configure,
unix/unix.c) [SMS]
- Extended the -j/--junk-dirs option to accept an optional value, the
number of directory levels to discard. Moved code to handle
directory junking out of the system-specific mapname[w]() functions
into the common extract.c:extract_or_test_entrylist[w](). Not
implemented on Tandem. Windows DLL sets uO.jflag from lpDCL->ndflag
as well as it can, but needs more than one bit to use the extended
capability. (extract.c, globals.h, unzip.c, unzpriv.h, acorn/acorn.c,

vms/unz_cli.cld, vms/vms.c, win32/win32.c, windll/windll.c) [SMS]
- Added C macro DIAG_SFX for developers to enable the "-v" diagnostic
report in UnZipSFX. Discouraged for normal use. (unzip.c) [SMS]
- On VMS, added HELP_TEXT as a builder option/target. Specifying
HELP_TEXT creates the text files UNZIP.HTX and UNZIP_CLI.HTX, which
are the output from "help unzip..." commands using the corresponding
.HLP help library source files. (vms/build_unzip.com,
vms/descrip.mms) [SMS]
- VMS CLI changes: Restore but deprecate /[NO]CASE_INSENSITIVE, replace
/CASE_MATCH (6.10a07) with more general /MATCH = CASE (-C). When C
macro WILD_STOP_AT_DIR is defined, add /MATCH = [NO]WILD_MATCH_SLASH
(-W). (vms/cmdline.c, vms/unzip_cli.help, vms/unz_cli.cld) [SMS]
- Changed C macro USE_ICONV_MAPPING to ICONV_MAPPING, and added "make"
macro ICONV to the Unix builder options to enable the feature. Added
ICONV_MAPPING to the "special compilation options" section of the
"-v" report. (unzip.c, zipinfo.c, beos/beocfg.h, beos/beos.c,
unix/configure, unix/unix.c, unix/unxcfg.h) [SMS]
- Format changes to ZipInfo header and totals report sections. The
totals section now includes separate member counts for directories
and files, and, where SYMLINKS is defined, links. A new option, -mc
(--member_counts, /[NO]MEMBER_COUNTS) allows the user to suppress the
new directories/files/links counts. Test archives have new-format
ZipInfo reports (without the new member counts, to accommodate
systems without symlinks). (testmake.zip, testmake_ppmd.zip,
unix/Makefile, unix/test_unzip.sh, unzip.c, unzip.h,
vms/test_unzip.com, zipinfo.c) [SMS]
- Volume labels can now be set on VMS (options: -$, --volume-label,
/VOLUME_LABEL). The destination device must be allocated, not
shared. (unzip.c, unzip.h, vms/vms.c) [SMS]
- Added option -k/--keep-permissions on AtheOS, BeOS, Unix, and VMS, to
control how archived permissions or protections are determined on
extracted files and directories. The default behavior has changed
from previous UnZip versions. Now, by default, on AtheOS, BeOS, and
Unix, the current umask value is applied (to the normal
user/group/other permissions). On VMS, the current default
protection is applied to the UIC-based (SOGW) protections. With -k,
the archived permissions are restored without regard to the Unix umask
or VMS default protection. (This was the default behavior in previous
UnZip versions.) With -k-, the archived permissions are ignored, so
only the Unix umask or VMS default protection is effective. (As
before, on VMS, directories are always created without any Delete
access.) Added new VMS CLI options /RESTORE = PROTECTION =
[LIMITED|ORIGINAL] for -k. Define the C macro NO_KFLAG to disable
the -k option, and restore the old behavior (or something like it).

vms/cmdline.c, vms/unz_cli.cld, vms/unzip_cli.help, vms/UNZIP_DEF.RNH,
vms/vms.c, vms/vms.h) [SMS]
- Added options -ka/--keep-acl (/RESTORE = ACL) on VMS, to control
restoration of ACL. Added VMS CLI option /RESTORE = OWNER (-X) to
control restoration of owner/UIC. With -k/--keep-permission
(/RESTORE = PROTECTION), these options allow independent control over
the restoration of ACL, protection, and owner/UIC. (man/unzip.1,
unzip.c, unzip.h, vms/cmdline.c, vms/unz_cli.cld, vms/unzip_cli.help,
vms/vms.c) [SMS]
- Added options on Mac OS X to provide better control over which
Mac-specific file attributes are _not_ restored on extracted files:
All extended attributes, -Je/--junk-extattr; Finder info,
-Jf/--junk-finder; Quarantine ("com.apple.quarantine"),
-Jq/--junk-qtn; Resource fork, -Jr/--junk-rsrc. (By default, all
are restored.) Note that the Quarantine attribute is one of the
extended attributes, so specifying -Je inhibits restoring the
Quarantine attribute, along with all other extended attributes. The
extended attribute features are available on Mac OS X 10.4 and later.
(The "xattr" command can be used to remove selected attributes after
extraction.) (fileio.c, unzip.c, unzip.h, unzpriv.h) [SMS]
- Experimental new builders for Microsoft Visual Studio (Visual C++)
2010. Optional feature selection for each program (project) is done
entirely using <project> Properties > Configuration Properties >
C/C++ > Preprocessor > Preprocessor Definitions > <Edit...>. Some
popular options (macros) are included, but are disabled by an easy to
remove "x_" prefix. The "unzip" project is used whether or not bzip2
compression support is desired. There is now no separate "unzipbz2"
project for UnZip with bzip2 support. The "unzip" and "unzipsfx"
projects have been marked as dependent on the "libbz2" project. If a
bzip2 source kit has not been installed in the "bzip2/" subdirectory,
then the "libbz2" project build will fail, but the "unzip" project
build should still succeed, so long as the C macro BZIP2_SUPPORT is
not defined. In the "Debug" configuration, DIAG_SFX is defined,
which enables the "-v" report in the UnZipSFX executable.

- Command-line syntax errors should now trigger a Usage explanation,
like the brief help (-h, /HELP) report. When triggered by an error,
this report now includes a listing of any options environment
variables (UNZIP, UNZIPOPT, UNZIP_OPTS, ...) which are defined (and
might be causing trouble in non-obvious ways). The -v (/VERBOSE)
report still shows all the options environment variables, whether or
not they're defined. If enough users object to the (bulky?) Usage
report, we may be persuaded to provide a way to disable it.

Deprecated /[NO]TIMES in favor of new /[NO]DECIMAL_TIME.
(vms/cmdline.c, vms/unz_cli.cld, vms/unzip_cli.help) [SMS]
- The Unix and VMS builders now support "PROD=subdir", allowing the
user to specify a destination subdirectory for product files (object
files, object libraries, executables, and so on), instead of getting
everything in the main, top-level directory on Unix, or the
automatically chosen subdirectory on VMS. This feature is intended
to make it easier to use one source tree for multiple build
configurations (different compilers, options, hardware architectures,
and so on). For details, see INSTALL and [.vms]INSTALL_VMS.txt (and
the builder files themselves). (INSTALL, unix/configure,

- Experimental implementation of symbolic links on Windows (Vista or
later?). To activate, define C macro SYMLINKS. Slightly improved
symlink error handling/messages on all symlink-capable system types.
On Windows XP, the build may work with SYMLINKS defined, but the
resulting UnZip executable may fail immediately with exit status
(Command Prompt: %ERRORLEVEL%, PowerShell: $LASTEXITCODE) -1073741511
(0xC0000139), "Entry Point Not Found", possibly with a pop-up message
which mentions CreateSymbolicLinkA (and KERNEL32.dll).

- Added initial support in ZipInfo for a proposed extra field type
(0x414c = "LA") containing attributes which are missing from the
local directory header. (unzpriv.h, zipinfo.c) [SMS]
- Added --version as a synonym for -v/--verbose. When used as the only
option, the program version, build options, and relevant environment
variables are displayed. (unzip.c, unzip.txt, unzpriv.h,

- Added library interface function UzpFeatures() to provide an
optional-feature string (a program-friendly edition of the "special
compilation options" section of the "-v/--verbose" report. (api.c,
unzip.h, libiz/izunzip_example.c, windll/vc10/windll32.def) [SMS]
- Added new -da/--auto-extract-dir (/[NO]AUTO_DIRECTORY) option to
specify a destination directory for extracted files which is derived
from the base name of the archive. For example, with -da, extraction
of "fred.zip" is done into subdirectory "fred" instead of into the
current directory. (On VMS, subdirectory "[.fred]".) Added new exit
status value, IZ_BADDEST (84), for failure to create automatic
destination directory. (fileio.c, process.c, unzip.c, unzip.h,

6.10c10 (18 Aug 2014):
- Added initial support for Windows directory symlinks (using a symlink
name with a trailing slash) on Unix, VMS, and Windows. (extract.c,
process.c, unzpriv.h, zipinfo.c, unix/unix.c, vms/vms.c,
win32/w32cfg.h, win32/win32.c) [EG, SMS]
6.10c11 (10 Oct 2014):
- Added option -0/--no-char-set (/NAMES = [NO]CHAR_SET) to suppress
certain character mapping (CP850) in some extracted file names.
("-0" is hyphen+zero.) Historically a particular character mapping
was applied (and still is, by default) to the names of archive
members which originated on a FAT or NTFS file system (typically on
an MS-DOS or Windows system). This can cause unexpected characters
in extracted file names if the corresponding (inverse) mapping was
not used when the archive was created. With -0/--no-char-set, the
extracted file name should agree with the name stored in the archive.
-0/--no-char-set is supported on all operating systems. On Unix (or
BeOS) it effectively overrides any -I/--iso-char-set or
-O/--oem-char-set option which may also be specified. Forum topic:

- Enable bzip2, LZMA, and PPMd compression support by default.
- On VMS, enable large-file support by default on Alpha and IA64
(with a run-time check on Alpha, using a new DCL script).
- On Unix, enable AES_WG support by default, if AES_WG source kit is
available.
- On VMS, notify user if AES_WG source is available but not used.

6.10c14 (03 Jan 2015):
- No news.
6.10c15 (12 Jan 2015):
- Included public-domain code from Peter Backes for the (obsolete)
Reduce compression method. (Some minor changes were made to clear
some diagnostics from modern compilers, and to accommodate inclusion
by unreduce.c.) To enable Unreduce support using the public-domain
code, define the C macro USE_UNREDUCE_PUBLIC. To enable Unreduce
support using the copyrighted Unreduce code, define the C macro
USE_UNREDUCE_SMITH (or, for compatibility with old code and
documentation, USE_SMITH_CODE), and supply the source file
unreduce_full.c. See INSTALL for details. The C macro
COPYRIGHT_CLEAN has been removed from the code and from the "UnZip
special compilation options" ("-v") report. The new USE_UNREDUCE_xxx
macros appear instead.

6.10c16 (18 Mar 2015):

the corresponding UnZip version. So, what would have been ZipInfo
version 3.10 will instead be designated version 6.10 (like UnZip).
(unzvers.h) [SMS]
- Added tentative, experimental-grade support for streaming input
archives on Unix systems. The C macro USE_EF_STREAM is now defined
by default to enable support for the new Zip "xl" (0x6c78) streaming
extra field. Define ARCHIVE_STDIN to enable support for streaming
input archives. Extensive refactoring of extract.c could have
introduced new defects. Some accommodation was attempted for
Windows, but not tested. (extract.c, fileio.c, globals.c, globals.h,

G.unipath_filename if set or translation of standard G.filename, to fix
bug where this was not set when using Unicode in Win32 and no Unicode
for this entry. (extract.c) [EG]
- Change (1 << 11) to UTF8_BIT macro. (extract.c, process.c) [EG]
- Bit 2 of internal attributes for an entry is the PKWare verification

(ttyio.c) [SMS]
- Replace obsolete test Zip archive, to give "make test" a chance to
succeed. (testmake.zip) [SMS]
- Add "testmake_zip" target to UNIX "make" file, to help in creating
testmake.zip. (Formerly not done on UNIX.) (unix/Makefile) [SMS]
- New command-line processing in ZipInfo miscounted non-option
arguments, causing loss of the heading and total sections in default
reports. (zipinfo.c) [SMS]
- New command-line processing in UnZipSFX lost the first non-option
argument (member to extract, not archive name). (unzip.c) [SMS]
- Various VMS CLI bad behavior involving /HELP and /VERBOSE.
(vms/cmdline.c) [SMS]
- Remove _orig files. (crypt.c_orig, crypt.h_orig, extract.c_orig,

- Rename bzip2 readme from 00README.IZ to README_bz2.txt.
(README_bz2.txt) [EG]
- Update Contents. Add lzma. (Contents) [SMS]
- Minor changes to Contents. (Contents) [EG]
- Update crypt to version 3.0. (crypt.h) [SMS]
- Update VCC6 project to look for AES_WG files in aes_wg.
(win32/vc6/unzip.dsp) [EG]
- Allow Total Disks (ecloc64_total_disks) to be 0, as some archive creator
out there sets this to 0 incorrectly instead of 1. However, probably
no reason we can't just go with it. This only is relevant for Zip64
archives. (process.c) [EG]
- Change i and b to unsigned in AES_WG endian test. (unzip.c) [SMS]
- Add possible fix for MINIX needing <unistd.h>. (unzpriv.h) [SMS, adapted
from user suggestion]
- New UNIX(-like) shell script for basic UnZip testing. Builder
changed to use it, instead of in-line actions. (unix/Makefile,
unix/test_unzip.sh) [SMS]
- VMS builders now generate module-ID options files. vms/unzip.opt and
vms/unzipsfx.opt have been removed from the kit. Add new NOCOMPILE, NOEXE,
LZMA, and TEST commands. Command-line options for the VMS DCL builder
should now agree better with those for Zip. (vms/build_unzip.com,
vms/descrip.mms, vms/unzip.opt (removed), vms/unzipsfx.opt (removed),
vms/optgen.com (new)) [SMS]
- Added VMS CLI option, /LICENSE, equivalent to --license. Change
VERBOSE to VERBOSE.COMMAND for verbose_command. Update to use -h and
-hh help options supported by new command line parser. (vms/cmdline.c,
vms/unz_cli.cld, vms/unzip_cli.help) [SMS]
- Significant updates to VMS Contents. (vms/contents) [SMS]
- New VMS DCL procedure for basic UnZip testing. New MMS/MMK builder
target, TEST, to run it, and CLEAN_TEST to clean up after it.
(vms/descrip.mms, vms/test_unzip.com (new), vms/install.vms) [SMS]
- Add definition of C macro _SZ_NO_INT_64 for LZMA on VAX.
(vms/descrip_mkdeps.mms, vms/descrip_src.mms) [SMS]
- Initial update to README. (README) [SMS]
6.10c05 (13 Aug 2011):
- Bug fix for array overflow and slight enhancement of "Available
options" listing. (unzip.c) [EG]
- Fix for improper argument count for -Z bug. (zipinfo.c) [EG, SMS]
6.10c06 (24 Aug 2011):
- Change UNZIP_BZ2VERS to UNZIP_BZIP2_VERS to be consistent with other
version macros. Set UnZip (compatible with) version based on inclusion
of BZIP2 or LZMA support. (extract.c, unzpriv.h) [SMS]
- Change %ld in a Trace() to %lld. (This would be incompatible with
Win32, which uses %I64d, but not a problem unless Trace() is used.)
Remove G.incnt < LZMA_PROPS_SIZE + 4 check from LZMA properties
length check. (extract.c) [SMS]
- Add (unsigned int) cast to ucsize assignment to fix 64-bit to 32-bit
assignment. (extract.c) [EG]
- Add (long) cast to G.ucsize_aes in IZ_MIN() to fix 64-bit to 32-bit
assignment. (fileio.c) [EG]
- Rename 7z* files to Sz*. (unzip.c, SzVersion.h, lzma/7zFile.c (remove),
lzma/7zFile.h (remove), lzma/7zVersion.h (remove), lzma/SzFile.c,
lzma/SzFile.h, lzma/SzVersion.h) [SMS, EG]
- Add encryption notices. (unzip.c) [SMS]
- Update LZMA Readme. (README_LZMA.txt) [SMS]
- Change 7z* to Sz*. Explicitly use sh to run test_unzip.sh.
(unix/makefile) [SMS]
- For VMS, update comments for SFX regarding AES_WG and LZMA. Note that
SFX does not include AES_WG by default. Change 7z* to Sz*.
(vms/build_unzip.mms, vms/descrip.mms, vms/descrip_deps.mms,
vms/descrip_src.mms) [SMS]
- Update VMS Install documentation. (vms/install.vms) [SMS]
- Minor updates to VMS test script. (vms/test_unzip.com) [SMS]
- Repackage Win32 VC 6 projects, creating new project unzipaes for AES_WG
and moving configurations dependent on AES files in the aes_wg
directory to that project. Remove AES_WG dependencies from unzip
project. Add LZMA configurations to the unzip and unzipaes projects.
Currently the VC 6 configurations depend on the LZMA files being present
(they are part of the source distribution so they should be). The user
ignores those files when they select a configuration that does not use
them. Added missing Release configurations. The ASM (assembly)
configurations are not updated yet to support AES_WG or LZMA.
(win32/vc6/unzip.dsp, win32/vc6/unzip.dsw, win32/vc6/unzipaes.dsp) [EG]
6.10c07 (12 Sep 2011):
- Change type of ucsize_lzma to SizeT. (extract.c) [SMS]
- CF_BZ now has "-DBZ_NO_STDIO" to build correct bzip2 variation.
(unix/configure, unix/Makefile) [AD]
- CF_BZ now contains "-D_FILE_OFFSET_BITS=64 -D_LARGE_FILES" if large
files supported. (unix/configure) [AD]
- Customize unzip unix/unxcfg.h for time.h et al. (unix/configure) [AD]
- Add fix for symlink bug. (See
http://comments.gmane.org/gmane.comp.version-control.git/181165).
From Andreas Schwab: "This only happens if you have more then 16K
entries and when one of the 16K entry infos is reused it happend to be
previously used for a symlink entry." Patch provided. (process.c) [AS]
6.10c08 (22 Nov 2011):
- Add (wchar_t *) casts to wstring malloc(). (extract.c) [SMS]
- Remove wchar.h include. Add parentheses around wide_string[]
assignment in for loop to quiet complaint by a particular compiler.
[SMS, AD]
- Add note regarding possible morphing of unzpriv.h to something more
like tailor.h. (Could happen.) Copy over UNICODE_SUPPORT comment
from Zip detailing the current plan for unifying Unicode code to just
three possibiities: UNICODE_WIDE, UNICODE_ICONV, and UNICODE_NATIVE.
Change "#define BSD" to "#define BSD 1". Copy over DBCS Japanese
support comment. Always include stdlib.h if UNICODE_SUPPORT defined.
Copy over wchar and langinfo support headers from Zip. Add MBCS
comment noting possible use of replacement functions when available.
Copy over in comments some Zip MBCS code. (unzpriv.h, unix/unxcfg.h)
[AD]
- Include unistd.h where available, mainly for SunOS. (lzma/szfile.h)
[SMS]
- Comment updates in top section. Attempts at making the Zip and UnZip
configure scripts similar. Formatting updates. Add message:
"Generating system-dependent flags...". Split up parameter list in
valid_vars. Remove -DUNIX from CFLAGS. Define AR_BZ for bzip2.
Change manuals output dir to manout. Default PORT to empty instead
of "unix." Default AES_WG, LZMA, IZ_BZIP2, and IZ_ZLIB to empty if not
already defined. Define PORT_SPEC for port specification method.
Remove OSDEP_C and OSDEP_S. Remove MANTAB. Minor changes to output
build messages. Assign default PORT setting. Set PORT_SPEC to I
(implicit) if PORT is unix, else E (explicit). Output UNAME_S as OS
name. Add quotes around some variables. Add tests for MinGW 64, MinGW
32, LLVM, LLVM Clang, LLVM GCC. Add Darwin check for obsolate -s
option. Add tests for Portable C (PCC), EKOPath, Intel, GNU C, CNU C
for Mac OS X, AIX. Update defines for CC_TST, CFLAGS_OPT, CFLAGS_TST,
and AR_BZ for each port. Add test for DJGPP, CYGWIN. Set build
configuration for various targets: msdos, os2, qdos, zos, zvm. Add
"fix me" note for assembler CRC code. Change some output error
messages to use ^^ prefix as in Zip. Add "No AES_WG encryption", "No
LZMA compression", "No BZIP2 compression", and "ZLIB not used" messages
as in Zip. Error message updates similar to Zip. Add comment
describing HAVE_HEADER_H, HAVE_DIR_HEADER_H, NO_HEADER_H,
NO_DIR_HEADER_H, FUNCTION=function, and NO_FUNCTION. Remove HPUX ANSI
test. Add off_t and UID/GID messages from Zip. (The UID/GID code, in
particular, may not be appropriate for UnZip, but this should be
corrected in a later beta.) Update sys/time.h messages. (Not sure if
these are appropriate to UnZip. It's possible that UnZip would work,
but that checking for unneeded features could prevent it from building.)
Add wchar.h checks. Update wide character support checks to match those
in Zip. Update check for missing functions. Add "FIX ME" note for
langinfo.h. Change ${CFLAGS} to ${CFLAGS_TST} in assignment. Update
MBCS functions check. Output end blank line. (unix/configure) [SMS, AD]
- Update Makefile instructions at top to be similar to Zip. Update
list of targets. Add additional instructions and guidance from Zip.
Update AR to change -cq to cq. Add note about OSDEP_H, OS_DEPOC, and
OSDEP_OS. Update note on Assembler to mention msdos/crc_i86.S. Remove
PGM_ZINFO from UNZIP_PGMS. User manout for output directory of manuals.
Put plain text versions of manuals in root directory as have
traditionally done. Use PGM_* variables to set BIN_* variables. Add
note about C files when cross compiling and PORT parm. Change note on
api.o rule from "object files" to "C Compile rule" for unzip DLL. Add
comment separator lines around AES code and LZMA code. Update BZIP2
test to use "@if [ flags_bz ];" instead of "@if test -f flags_bz;".
Change "-> zips' to "-> unzips". Change manl rule to manout. Update
text output rules for manuals based on Zip updates including using man
instead of nroff. Add "Running: unix/configure" message. Add PROD
parameter to unix/configure. Add note on BZIP2 flags. Add PGM_ZINFO to
clean rule. Add clean_docs rule for cleaning the plain text docs as
was done in Zip. Update install rule. Remove duplicate "Originally
tested under Sun" comment. Add generic build warning message. Rephrase
some comments for generic rules. Update rules list for specific ports.
Remove OSDEP_C and OSDEP_S from linux_dos rule. Remove some space from
comments and messages. (unix/Makefile) [SMS, AD]
- Add compiler identification for NeXT DevKit, MinGW 64, MinGW 32, LLVM
Clang, LLVM Apple GCC, LLVM GCC, Portable C, EKOPath C, Intel C, GCC, and
SunPro C. Ignore case of "CRAY" define. Reformat IBM version. Reformat
sprintf() lines for specific compiler versions. Change (bad) Mac OS X
message string '" (Mac OS X")' to '" (Mac OS X)"'. (unix/unix.c) [AD]
6.10c09 (8 May 2014):
- Minor code tidying: UZbunzip2() and UZlzma() are now static.
(extract.c, unzpriv.h) [SMS]
- A bare "#if" directive embedded in a multi-line comment block
confused old C preprocessors (SunOS 4.1.4 bundled C, VAX C V3.1-051).
(unzpriv.h) [SMS]
- Less lame handling of LZMA and PPMd data structures. More things are
allocated and/or initialized once per job, rather than once per
archive member. (extract.c, globals.h, process.c) [SMS]
- Removed definition of unused LZMA- and PPMd-related C macro _7ZIP_ST
from builders. (unix/configure, vms/build_unzip.com,
vms/descrip_src.mms) [SMS]
- Miscellaneous code tidying for user-triggered progress message on
VMS: Portability to old VAX versions, coping with batch mode, better
comments and messages. (vms/vms.c, vms/vmscfg.h) [SMS]
- Removed lzma/Alloc.c and lzma/Alloc.h (MyAlloc() and MyFree()
functions). (extract.c, unix/Makefile, vms/descrip_src.mms) [SMS]
- Remove (unused) lzma/SzFile.c and lzma/SzFile.h. (unix/Makefile,
vms/descrip_src.mms) [SMS]
- Bad hard-coded string length in message function could put a spurious
NUL character into messages. (Typically invisible on screen, but
ugly in redirected output.) (fileio.c) [SMS]
- On Unix, "make clean" missed some spots. (unix/Makefile) [SMS]
- A user-specified CFLAGS value for UNIX(-like) builds no longer needs
to include "-I.". (unix/configure) [SMS]
- Some Clang and GCC versions would emit many "warning: format string
is not a string literal" or similar diagnostics. The Unix builders
now add compiler options, "-Wno-format-security" and/or
"-Wno-format-nonliteral", to suppress these, where appropriate.
(unix/configure) [SMS]
_ Changed C macros USE_BZIP2, USE_DEFLATE64, USE_LZMA, USE_PPMD, and
USE_UNSHRINK to BZIP2_SUPPORT, DEFLATE64_SUPPORT, LZMA_SUPPORT,
PPMD_SUPPORT, and UNSHRINK_SUPPORT, respectively, for clarity and
consistency with Zip. (INSTALL, explode.c, extract.c. fileio.c.
funzip.c. gbloffs.c. globals.h. inflate.c, process.c, ubz2err.c,

msdos/makefile.dj2, msdos/makefile.wat, os2/os2cfg.h, unix/configure,
vms/build_unzip.com, vms/descrip_src.mms, win32/Makefile,
win32/Makefile.gcc, win32/Makefile.wat, wince/punzip.h) [SMS]
- Changed the "special compilation options" section of the "-v" report
to agree better with that of Zip. Added explanations for some more
options. (unzip.c) [SMS]
- Changed to use the new C macro, NO_TRADITIONAL_CRYPT, as in Zip, to
control (disable) compilation of code specific to traditional
encryption, allowing AES_WG encryption without traditional
encryption. (crypt.c, crypt.h, fileio.c, unzip.c, unzpriv.h) [SMS]
- Adopted a suggestion from Ireneusz Hallmann to use an alternate
buffer in more situations in the DLL, to solve a problem with data
corruption when inflating to memory. Adapted another suggestion for
a better window size calculation. The old method gave poor results
for buffer sizes which were not powers of two. (inflate,c) [IH, SMS]
- Fixed many problems when building with REENTRANT defined, mostly in
the new command-line option code, but also in ppmd_read_byte() and
the user-triggered progress message. Reformed globals access in
VMS-specific stamp_file(). (extract.c, unzip.c, unzpriv.h,
zipinfo.c, vms/vms.c) [SMS]
- Added "aesw" to the table of compression method names used in a
ZipInfo report. ("u###" was appearing for method 99 in reports.)
(zipinfo.c) [SMS]
- Repaired lame punctuation in SFX "Must quote upper-case options"
message on VMS. (unzip.c) [SMS]
- Renamed C macro APL_DBL_SFX to APL_DBL_SUFX to reduce confusion with
self-extracting "SFX". (extract.c, fileio.c, unix/macosx.h) [SMS]
- Added some minimal/lame support in the unix/zipgrep script for (up to
four) GNU long-form options for egrep, and fixed some lame error
handling (when the "unzip -Z1" command failed, for example). Added
"\" escapes for globbing characters ("*", "?", and "[") in archive
member names. Many limitations and problems remain. (unix/zipgrep)
[SMS]
- Renamed "lzma" directory to "szip". (Contents, INSTALL, extract.c,
globals.h, unzip.c, unix/configure, unix/Makefile, vms/build_unzip.com,
vms/descrip_deps.mms, vms/descrip_mkdeps.mms, vms/descrip_src.mms) [SMS]
- Changed Mac OS X system-specific code to use "/..namedfork/rsrc" as
the suffix for resource fork access on Intel, staying with "/rsrc" on
PowerPC. Define the C Macro APPLE_NFRSRC as 0 (on Intel) or 1 (on
PowerPC) at build time to override the automatic decision. (We believe
that all PowerPC-compatible OS versions accept "/rsrc", and all
Intel-compatible OS versions accept "/..namedfork/rsrc".) Using "/rsrc"
on Mac OS X 10.7 (Lion, Intel-only) caused spurious "Not a directory"
messages, and resource forks were not properly restored. (unzip.c,
unix/macosx.h) [SMS]
- UnZip failed to extract an archive member with a null name (silently
on VMS, with a mesage, "mapname: conversion of failed", on Unix).
Spurious error messages like ": mismatching "local" filename (fred)"
(where "fred" was some previously processed member name) were also
possible. (Info-ZIP Zip uses "-" as the name for an archive member
created from standard input, but the .ZIP standard allows a null name
for this case.) Now, UnZip extracts a null-name archive member as
"-" (C macro: NULL_NAME_REPL). On VMS, an error message was added,
similar to the one on UNIX, and on UNIX, the message was clarified.
(fileio.c, unzpriv.h, unix/unix.c, vms/vms.c) [SMS]
- "unzip -t" silently detected an unexpected end-of-file condition when
reading an archive, leading to an unexplained "At least one error was
detected" message. An "Unexpected end-of-file" message has been
added to reduce the mystery in this case. (extract.c) [SMS]
- Java "jar" archives with over-simplified header info were interpreted
as coming from MS-DOS, causing UTF-8-encoded file names to be damaged.
A Java "CAFE" extra block is now detected, and inhibits this
inappropriate name conversion. A new "--jar" option lets the user
force this behavior when an archive lacks a "CAFE" extra block.
http://sourceforge.net/p/infozip/support-requests/10/ (extract.c,
fileio.c, unzip.c, unzip.h) [SMS]
- Added Java "CAFE" extra field type to ZipInfo reports. (zipinfo.c)
[SMS]
- Changed some declarations to accommodate a type change in zlib
version 1.2.7. (globals.h) [SMS]
- UnZipSFX could fail (SEGV) on systems with backslash ("\") file path
separators (MSDOS, Windows, ...), if a list of member names to be
extracted was specified on the command line. (unzip.c) [SMS]
- Added a #ifndef condition to avoid redefining the C macro
HAVE_TERMIOS_H on Cygwin. (unix/unxcfg.h) [SMS]
- Fixed assembler testing in configure script. Defining NO_ASM or
NO_ASM_CRC in LOCAL_UNZIP disables use of assembly code for CRC.
(unix/configure) [SMS]
- Added Linux Exec Shield .section directive to assembly code, as in
Zip. (crc_i386.S) [SMS]
- Added a check in DLL unzip() for proper NULL termination of argv[].
(unzip.c) [SMS]
- Revised VMS builders to make it easier to generate the help files
(only). (vms/build_unzip.com, vms/descrip.mms) [SMS]
- Changed to avoid conflict between a user definition of the C macro
NO_EXCEPT_SIGNALS and an automatic one. (unzip.c) [SMS]
- Disambiguated some option-related error messages. (unzip.c) [SMS]
- Changed, on VMS, the way a "-d" (/DIRECTORY) destination directory is
tested for validity. Previously, some VMS-invalid directory
specifications (such as "." or "..") would generate no error, and
then be (silently) ignored.
- Reformed the multi-value C macro CRYPT into simpler (binary)
IZ_CRYPT_ANY and IZ_CRYPT_TRAD. The actual encryption code should
now use only IZ_CRYPT_AES_WG and IZ_CRYPT_TRAD (plus IZ_CRYPT_ANY,
derived from them). At build time, users specify more controlled
options: CRYPT_AES_WG, CRYPT_AES_WG_SFX, CRYPT_TRAD_SFX, NO_CRYPT,
NO_CRYPT_TRAD. (crypt.c, crypt.h, ebcdic.h, extract.c, fileio.c,
funzip.c, gbloffs.c, globals.h, INSTALL, ttyio.c, ttyio.h, unzip.c,
unzpriv.h, amiga/filedate.c, qdos/qdos.c, windll/windll.c) [SMS]
- Changed C macro USE_UNZIP_LIB$INITIALIZE to USE_UNZIP_LIB_INITIALIZE
for consistency with Zip, where Sun C objected to the "$" in the
corresponding code. (vms/vms.c) [SMS]
- Changed some assembler-related details, including the test for an
"_" prefix on global names. (unix/configure, unix/Makefile) [SMS]
- Supposedly, the "-s" (--space_to_uscore) option became OS-generic in
6.10c01, but its implementation relies on OS-specific mapname()
processing, and there was none on Unix or VMS. It may still be
missing on other, more obscure systems. (unix/unix.c, vms/vms.c) [SMS]
- Changed the archive file default file spec on VMS from "[]*.ZIP" to
".ZIP", to avoid undesired behavior in some unusual cases.
(vms/vms.c) [SMS]
- VMS-specific problem could cause "unzip -a" to truncate the last line
in a text file if it lacked a normal line ending (like LF). (This
problem was close to, but different from, the similar one which was
fixed in version 6.10c01.) (vms/vms.c) [SMS]
- The Unix builders detected a UID and/or GID bigger than 16 bits, but
then defined the wrong C macro, disabling support for the new "ux"
extra block. This could prevent UnZip (-X) from restoring UID and
GID on files extracted from archives created by Zip 3.0 or later,
where the new "ux" extra block was used. Never defining the right C
macro also hid some defective code, which would cause a build failure
if the right C macro was defined. Also, the "-v" report did not
mention this option (IZ_HAVE_UXUIDGID). Forum topic:
http://www.info-zip.org/phpBB3/viewtopic.php?f=3&t=402
(process.c, unzip.c, unix/configure) [SMS]
- VMS CLI UnZip executables (UNZIP_CLI.EXE) were being built with a
ZipInfo module (zipinfo.c) which was compiled for the Unix-style
interface, not the VMS CLI interface. An obvious symptom was a
Unix-style usage guide instead of a VMS CLI-style usage guide.
(vms/build_unzip.com, vms/descrip.mms, vms/descrip_mkdeps.mms,
vms/descrip_src.mms) [SMS]
- With -c (--to-stdout, /SCREEN) or -p (--pipe-to-stdout, /PIPE),
various progress messages ("Archive: xxx", "inflating: yyy", and so
on) were sent to stdout along with the extracted data, and only
-q (--quiet, /QUIET) could stop them. Now, with -c or -p, these
messages should be sent to stderr, making them visible to the user
without corrupting the extracted data stream. (fileio.c, unzpriv.h,
vms/vms.c) [SMS]
- Attempt to support Zip64 in fUnZip. Changed to skip directory
members at the beginning of an archive, instead of doing nothing when
the first archive member was a directory. Changed some messages and
exit status codes. Still crude in many places. (funzip.c) [SMS]
- With UNICODE_SUPPORT, UnZip could fail (SIGBUS, SIGSEGV,
%SYSTEM-F-ACCVIO, ...) when processing a non-Unicode name which
contained character codes above 127. More thought/work may be needed
here. http://sourceforge.net/p/infozip/bugs/40/ (extract.c) [SMS]
- Changed the DLL and object-library forms of the UnZip main entry
point function not to look for "zipinfo" in argv[0]. To get ZipInfo
mode, specify "-Z" in argv[1]. (unzip.c) [SMS]
- Changed iconv code to use memset() instead of bzero(), for
consistency and portability. Added a missing free(). Added
ICONV_ARG2 macro to facilitate user addition of a "const" type
qualifier to satisfy Sun C. Moved loose global storage into the
general globals structure. Copied newer Unix code into BeOS.
(beos/beocfg.h, beos/beos.c, globals.h, unix/unix.c, unix/unxcfg.h,
unzip.c, unzpriv.h, zipinfo.c) [SMS]
- -M (/MORE) used bad carriage control on VMS, adding spurious blank
lines to the output. Changed the prompt function on VMS to use the
same output file as the message function (stderr or stdout) to avoid
this. (fileio.c, globals.h) [SMS]
- Revised VMS DCL builder to recreate object libraries when not
compiling (NOCOMPILE). (vms/build_unzip.com) [SMS]
- Fixed some bad behavior (program aborts or loops, or faulty memory
access) caused by (intentionally) defective/corrupt archives.
Reported by OUSPG ("https://www.ee.oulu.fi/research/ouspg/"),
CVE-2015-7696. Removed some harmless but redundant free() instances
from extract.c. (crypt.c, crypt.h, extract.c, fileio.c, funzip.c,

- memcpy() was being used in some cases on overlapping buffers, which
could cause bad extracted data (and "bad CRC" errors) on some
systems. Forum topic:
http://www.info-zip.org/phpBB3/viewtopic.php?f=7&t=406
New code uses memcpy() only on disjoint buffers. New C macros
replace old NOMEMCPY: Define C macro NO_SLIDE_MEMCPY to disable use
of memcpy(). Define SLIDE_MEMMOVE to enable use of memmove() for a
case where it works. Limited testing suggests that using memcpy() is
faster, but using memmove() is not, so that's the default scheme, but
we're open to evidence reports. (explode.c, inflate.c) [SMS]
- Changed LLVM Clang compiler version identification to cope with v1.x,
where __clang_major__ and friends were not defined. (unix/unix.c)
[SMS]
- Made the configuration test for lchmod() stricter, to detect a "not
implemented" compiler warning message (Clang and GCC on GNU/Linux).
(unix/configure) [SMS]
- Changed the definitions of macros _ISO_INTERN and _OEM_INTERN on Unix
to use function charset_to_intern() (now not static) directly, instead
of using inline functions, iso_intern() and oem_intern() (now gone).
HP-UX bundled C compiler (at least) does not support the keyword
"inline". (beos/beocfg.h, beos/beos.c, unix/unix.c, unix/unxcfg.h,
unzip.c) [SMS]
- Added macro "Tracing", defined when macro "Trace" is non-empty, for use
where Trace() was the only thing in the body of an "if" statement,
and Clang complained, "if statement has empty body". (extract.c,
unzpriv.h) [SMS]
- Stopped some memory leaks, mostly related to the new command-line
parser. Removed declarations and use of obsolete global name array,
fnames[]. Removed the unused global pointer argument from
free_args(). Removed redundant call to free_G_buffers() from
process_zipfiles(). Track and free transient-use command-line option
value storage. In free_G_buffers(), added calls to free() for the
archive name and for retained command-line option values: extraction
directory (-d) and password (-P). Changed API functions to use
dynamic storage for the archive name (which may now be free()'d).

- In Unix builders, accept user-specified CFLAGS_OPT macro to override
automatic compiler optimization options setting. For debugging, for
example, one might specify "CFLAGS_OPT='-g -O0' LFLAGS2=-L.". (A
non-null value is required for each. "-L." should be harmless for
LFLAGS2.) Stopped putting redundant "-L." linker options into
"flags". (unix/configure) [SMS]
- Added some conditionality for SGI IRIX. (Knowing nothing, we assume
that large-file support is still missing on SGI IRIX.)

- Added definition of HAVE_LOCALE_H to Windows-specific configuration

- Changed VMS builders to use explicit (CC) /NOLIST and (LINK) /NOMAP
qualifiers by default, to reduce unexpected clutter in batch mode.
(vms/build_unzip.com, vms/descrip_src.mms) [SMS]
- Changed APIhelp() interface to deal with the new command-line parser.
Converted tabs to spaces in text. Removed a BEL code from an error
message. Added text for UzpMainI(). Added NULL termination to
example argv[] arrays. Added apihelp.c to the Unix and VMS builders,
primarily for testing. (It's normally disabled, unless API_DOC is
defined.) (apihelp.c, unzip.c, unzpriv.h, unix/Makefile,

- Fixed a problem where callable UnZip (or any build with the C macro
REENTRANT defined) could try to free() the main-program argv[],
instead of our local copy. (unzip.c, zipinfo.c) [SMS]
- Removed a Unicode memory leak, and improved some sub-optimal code
based on suggestions from Dmitry ??????. (fileio.c, process.c,
win32/win32.c) [Dmitry, SMS]
- On non-VMS systems, an I/O error while extracting a file (disk full,
or similar) caused an interactive query ("write error (disk full?).
Continue? (y/n/^C)"), even if there was no interactive user, causing
the program to hang. Now, by default, such an I/O error is fatal.
To restore the query, define the C macro I_O_ERROR_QUERY at build
time, but the query code now checks stdin using isatty(), and skips
the query if stdin is not a terminal. (fileio.c, unzpriv.h)

- In "-vl" (/LIST /FULL) reports, an unexpectedly large compression
method value (>999) caused a (mostly harmless) buffer overflow, and
spoiled the report format. Now, values less than 1000 are displayed
as before, using a three-digit decimal format, "Unk:ddd", but larger
values are displayed using a four-digit hexadecimal format,
"UnkXXXX". http://sourceforge.net/p/infozip/bugs/27/ (list.c) [SMS]
- In ZipInfo reports, an unexpectedly large "version made by" value
(>99) caused a (mostly harmless) buffer overflow, and could spoil the
report format. Now, for system types where space always allows,
large values should always be displayed properly. For VMS, a more
careful calculation is done to determine space requirements, and
large values should be displayed properly when space allows. Forum

CVE-2014-9913. (zipinfo.c) [quanww, sanvila, SMS]
- Added some crude, optional, dynamic memory tracing diagnostic
capability for use by developers. (api.c, crypt.c, envargs.c,
extract.c, fileio.c, funzip.c, globals.c, inflate.c, match.c,
memdiag.c, process.c, timezone.c, unshrink.c, unzip.c, unzpriv.h,
unix/unix.c, win32/win32.c) [SMS]
- On Windows, with Unicode support, a buffer overrun in pathname
storage could cause a variety of problems, including spurious error
messages and program failure. That problem should be solved. Some
buffers were allocated with a few bytes more than necessary. Some
code which was needed only for developer diagnostic tracing was being
compiled and executed always. A reform making the global array
unipath_widefilename fixed instead of dynamic can be reversed by
defining the C macro DYNAMIC_WIDE_NAME. (extract.c, fileio.c,
globals.h, memdiag.c, process.c, unzip.c, win32/w32cfg.h,
win32/win32.c) [SMS]
- Changed behavior involving files which appear to have VMS version
numbers (names ending with ";ddd", where "ddd" is a decimal number),
and option "-V" (--keep-versions, /[NO]VERSION). Previously, UnZip
would, by default, strip these apparent VMS version numbers when
extracting files, and the "-V" option was required to prevent this,
even when the file was not archived on a VMS system. Thus, a Unix
file named "fred;123" would normally be extracted as "fred", unless
"-V" was specified to prevent this damage. Now, on non-VMS systems,
UnZip should strip apparent VMS version numbers only from files which
were archived on a VMS system. Specify "-V" explicitly to keep
version numbers even on VMS-archived files. Specify "-V-" explicitly
to strip apparent VMS version numbers from all files regadless of
where they were archived (the old default behavior). Behavior on VMS
systems is unchanged. (acorn/acorn.c, amiga/amiga.c, aosvs/aosvs.c,

- Changed the VMS DCL test script to give SFX tests some chance of
working on VMS versions before V6.0, where SET FILE /ATTRIBUTES is
not available. Added an explanation to the VMS-specific installation
instructions. (vms/INSTALL_VMS.txt, vms/test_unzip.com) [SMS]
- Some conditional code conditions were misplaced, causing compiler
warnings and/or bad behavior when some combinations of optional
compression and/or encryption options were enabled in UnZip SFX.

- Added a Windows cmd test script, but the builders don't (yet?) run it
automatically. Added code to set appropriate exit status values in
the Unix and VMS test scripts. (unix/test_unzip.sh,
vms/test_unzip.com, win32/test_unzip.cmd) [SMS]
- Changed VMS exit status code to SS$_NORMAL for success instead of a
facility-specific code (%x17A28001). This agrees with most VMS
utilities, and with UnZip versions before 6.10a02. Define C macro
OK_USE_FAC to use the facility code in all cases. (vms/vms.c) [SMS]

- On Windows, conflicts with anti-virus programs could cause avoidable
errors, "CreateFile() error 32 when trying set file time". ("32" is
ERROR_SHARING_VIOLATION.) A similar problem when setting NT Security
Descriptor data (-X) has not been reported, but seems similarly
likely. Now, when CreateFile[AW]() fails for this reason, it is
retried according to C macros IZ_CREATEFILE_xxx, defined in
win32/w32cfg.h. Currently, a fixed time limit is used, which may be
inadequate for large files. Users who still experience the problem
are encouraged to report the circumstances.

- On Mac OS X, extended attributes (such as "com.apple.quarantine")
were erroneously treated as more resource-fork data, so the
extracted file did not get the proper attributes, and its resource
fork was corrupted. These attributes should now be set correctly.
Define the C macro NO_APPLE_XATTR at build time to disable the code
to set extended attributes. (fileio.c, globals.h, process.c,

- Moved definitions of multi-character option ID codes from individual
main program modules to a common header file. (unzip.c, unzpriv.h,
zipinfo.c) [SMS]
- On Mac OS X, with "-d exdir", AppleDouble "._" file names were
mishandled, causing Finder info and resource fork data to be lost.
Some Mac-specific name handling code has been moved from the general
extract.c:extract_or_test_entrylist() to a new OS-specific function,
unix/unix.c:revert_apl_dbl_path(). (extract.c, fileio.c, globals.h,
unzpriv.h, unix/unix.c) [SMS]
- On Mac OS X, when archive member patterns were specified explicitly,
including with a -x/--exclude option, AppleDouble "._" file names
were mishandled, causing Finder info and resource fork data to be
lost, or otherwise mishandled. This happened because a normal name
and the corresponding "._" name might not match the same patterns, so
one of the two parts might be processed while the other was not.
Now, when Mac attributes are being restored (no -J/--junk-attrs
option, and the destination volume supports attributes), an
AppleDouble "._" archive member should be processed if the
corresponding normal archive member is. (extract.c) [SMS]
- On Mac OS X, setting non-data-fork attributes/data on a file could
give it a new modification time, even if the user requested that its
archived modification time be restored. (unix/unix.c) [SMS]
- On Mac OS X, with an Intel CPU, UnZip tried to access a resource fork
using the old "/rsrc" suffix instead of the newer "/..namedfork/rsrc"
suffix, and this failed. After some recent code restructuring,
unzip.c was not including unix/macosx.h as needed, so the C macro
APPLE_NFRSRC was not being defined properly. An undefined
APPLE_NFRSRC should have been detected, but was not. (api.c,

- A user response longer than eight characters to an interactive query
(like, say, "replace XXX? [y]es, [n]o, [A]ll, [N]one, [r]ename: ")
could be only partially consumed, leaving excess characters to be
read by a later interactive query, without any additional user

- Changes to accommodate old K&R-style C compilers: Changed some API
function declarations/prototypes to remove prototypes where they are
not supported. Changed the object-library example program to work
when prototypes are not supported. Renamed some members of the
_version_type structure to avoid conflicts with macros "major" and
"minor" on SunOS 4.1.4. Added some type casts to clear some compiler
complaints. Indented a "#error" directive. Added a missing ranlib
command to the "make" rule for libizunzip.a on Unix. (api.c,
apihelp.c, funzip.c, unzip.c, unzip.h, libiz/izunzip_example.c,

- Restructured "man" documentation directories. Now, "man" source
files (*.1) are supplied in a "man/man1/" directory, allowing direct
use of a "man -M ./man" command in the kit directory. Formatted
"man" output files (*.txt) are now supplied in a "docs/" directory.
(INSTALL, README, unix/configure, unix/Makefile) [SMS]
- On Unix systems, a temporary object library used during a build for
some optional feature (for example, liblzma.a) could easily collide
with an existing system-wide object library or shared object, and
cause a link failure (undefined symbol, or similar). Now, these
temporary object library names include a distinctive prefix,
"iz_prvt_" which should be enough to avoid the problem.
(unix/configure, unix/Makefile) [SMS]
- The Unix builders now support use of the "make" macro PREFIX to
specify a destination directory tree with the "install" target, and
MANSUFX replaces MANEXT for modifying the names of the installed
"man" files. The "install" target was trying build programs as well
as just copying them, which was more than it knew how to do. Some
obsolete, disfunctional, or experimental targets ("generic_XXX",
"*shlib*") have been removed. The rules used to create the formatted
manual (".txt") files now use "man -M", allowing them to work with
non-GNU "man" programs.
- Changed the name of the function zipinfo.c:zipinfo() to zipinform(),
to clear a compiler complaint on z/OS (CCN3571, "The external name
zipinfo must not conflict with the name in pragma csect or the csect
name generated by the compiler."). (process.c, unzpriv.h, zipinfo.c)

- Removed some decisions involving "man" file names and "bin" and "man"
installation directories from the unix/configure script, allowing
unix/Makefile to follow explicit user instructions. ("If you don't

- If memory allocation failed in the unmatched-name detection code for
file list and -x/--exclude (/EXCLUDE) list names, no notice was

- Fixed a buffer-overflow problem reported by William Robinet, in

- Changed behavior on non-VMS systems for the "rename" option in
interactive file-system conflict resolution queries ("replace XXX ?
[y]es, [n]o, [A]ll, [N]one, [r]ename:"). Previously, the "-d exdir"
extraction directory could be added to a user-specified file-system
path which was a relative path (but not to an absolute path). This
was confusing, because the path name shown in the query already
included this directory, so a reasonable copy+paste operation could
result in the extraction directory being added a second time. Now,
the "-d exdir" extraction directory is added to an archive path (when
it is transformed to a file-system path), and not to a path which is
already a file-system path (like a "rename" path). Define the C
macro EXDIR_RENAME to restore the old behavior. Not yet changed on
obsolete systems, pending user requests (and testing on popular
systems). Added a space before the "?" in the query message to help
with copy+paste activity. (atari/ataricfg.h (new), beos/beocfg.h,

- Changed behavior on Windows systems with Unicode support enabled
(NO_UNICODE_SUPPORT not defined). Previously, action messages
("extracting:", "inflating:", and so on) showed the archive member
path/name, not the destination file-system path/name, as was done
when Unicode support was disabled (or on non-Windows systems).
Similarly, the wrong name could be shown in interactive file-system
conflict resolution queries, as described above. Some related code
reorganization changed some variable names in non-Windows-specific

- Since version 6.10b03, if the "external file attributes" for an
archive member was zero, typically when the archive was created from
a FAT file system (or similar, so, lacking UNIX-like permissions),
and then the archive member was extracted on a VMS system, the
resulting file and directory permissions could be defective.
(vms/vms.c) [SMS]
- The zipgrep shell script was erroneously adding backslash escapes to
pattern strings, making some legitimate egrep patterns behave like
simple grep patterns. The zipgrep "usage" text now reminds the user
(and the developer) that it uses egrep. (unix/zipgrep) [SMS]
- UnZip gave unhelpful error messages when trying to process archive
members with AES_WG encryption and an unsupported compression method
(for example, JPEG or WavPack). Now, if AES_WG encryption is not
supported, then the "skipping" action message should complain about
"AES_WG_encr". If AES_WG encryption _is_ supported, then the
"skipping" action message should complain about the actual
unsupported compression method. (AES_WG encryption is denoted by a
fake "compression method" of 99, and the actual compression method is
stored in an AES_WG extra block. In some cases, the AES_WG "99"
value was being used instead of the actual value from the extra
block.) (extract.c) [Elvis Angelaccio, SMS]
- Revised some "UT"-related comments. (process.c) [SMS]
6.1c21 (12 May 2017):
- Changed the Windows DLL UnZip-like example program to send its
example-specific messages to stderr instead of stdout. This allows
the ZipInfo test in the Windows test command script
(win32/test_unzip.cmd) to pass. (windll/unzipstb.c) [SMS]
- Extended the crude, optional, dynamic memory tracing diagnostic
capability for use by developers to some VMS-specific modules.
(vms/cmdline.c, vms/vms.c) [SMS]
- The -da/--auto-extract-dir (/[NO]AUTO_DIRECTORY) option, to create a
destination directory based on the archive name, was truncating the
archive name at the leftmost dot, not the rightmost dot, leading to a
truncated directory name if the archive name included multiple dots.

- The new command-line parser was not properly handling a double hyphen
("--") token, which should stop option interpretation. When that was
changed, some loose global variables were moved into the main globals

- On Unix, file date-time values in a "UT" (0x5455) extra field block
could be ignored if a modern "ux" (0x7875) UID/GID block followed it
(which would be usual for an archive created bu Zip 3.x). The DOS
(local) modification date-time (which is always present) would then
used instead, but it has a two-second resolution and no timezone
information. The result was a file modification date-time with an
even number of seconds, even if the original value was odd, and
unexpected hours/date caused by the loss of timezone information.

- In ZipInfo ("-Z", /ZIPINFO) short-format ("-s", /SHORT, default)
reports, an unexpectedly large compression method value (>999) caused
a (mostly harmless) buffer overflow, and spoiled the report format.
Now, values less than 1000 are displayed as before, using a
three-digit decimal format, "uDDD", but larger values are displayed
using a four-digit (unlabled) hexadecimal format, "XXXX".

(zipinfo.c) [Alexis Vanden Eijnde, Tyler Hicks, SMS]
- On VMS, a "%" character in an archive name, or in an archive member
directory or file name, could cause spurious error/warning messages
when a caret-escaped percent sign ("^%") was erroneously interpreted
as a one-character wildcard. Typical messages included:
(unzip -T name_with_^%_sign.zip):
[ Modify file QIO failed. ]
[ %SYSTEM-W-NOMOREFILES, no more files ]
warning: cannot set time for: dev:[dir]name_with_^%_sign.zip;1
(extracting/creating a directory with a "%"):
warning: set-dir-attributes failed ($qiow mod) for dev:[dir]x.DIR;1.
[ %SYSTEM-W-NOMOREFILES, no more files ]
warning: set times/attribs failed for dev:[dir]
failed setting times/attribs for 1 dir entries
(extracting a regular file with a "%"):
[ Cannot create (QIO) output file dev:[dir]name_with^%_sign.txt ]
[ %SYSTEM-W-BADFILENAME, bad file name syntax ]
and so on. In a related problem, on VMS, match.c:iswild() ignored
caret escapes, causing many non-wildcard names to be considered
wildcard names. Also, since VMS V7.2 on non-VAX, "?" is a
one-character wildcard, equivalent to "%", but was not treated as
such. (Correcting this problem makes possible the first of the
problems shown above.) For example:
($unzip -T name_with_^%_sign.zip)
unzip: cannot find any matches for wildcard specification
"name_with_^%_sign.zip".

- Added "ZCONST" to an argument declaration in action_msg() to clear a
GCC compiler warning on AIX. (extract.c) [SMS]
- Changed some archive data buffer types from "char" to "unsigned
char". (extract.c, globals.c, globals.h, fileio.c, process.c,

- Added code to detect (and, for now, mostly ignore) a Central
Directory Digital Signature. Previously, its presence could cause a
spurious informational message: "note: didn't find
end-of-central-dir signature at end of central dir." Now, it
triggers an informational message saying that the digital signature
data were detected but ignored. (consts.h, extract.c, globals.c,
globals.h, list.c, process.c, unzpriv.h, zipinfo.c) [Jakub Martisko,

- When processing a Zip64 (large-file) archive, "unzip -T" could
generate a spurious informational message, "note: didn't find
end-of-central-dir signature at end of central dir." Otherwise, the
results seem to have been correct. (list.c) [SMS]
- Added a Windows-specific "#pragma comment" directive for the bzip2
object library in the UnZip object library example program, solving a
build failure on Windows. (libiz/izunzip_example.c) [SMS]
- In the Unix builder, added "LANG=C" to the generation rules ("man",
nroff) for the ".txt[r]" plain-text formatted "man" files. This
prevents a Unicode locale at build time from affecting the results.
(unix/Makefile) [SMS]
- Changed a variable type, and added type casts to clear some (VS 2017)
compiler warnings involving AES_WG encryption on x64 (using
aes_wg/fileenc.c:fcrypt_init()). (api.c, crypt.c) [SMS]
- Tidied Windows vc10 builders, mostly for x64, but some more generally.
The bzip2 code (bzip2\compress.c) may trigger a harmless warning on
x64. Made AES_WG support the default (C macro: CRYPT_AES_WG).

- Build failed with an old C compiler (HP-UX PA-RISC bundled). In
process.c:process_zipfiles(), an insufficiently primitve variable
declaration. In unzip.c:UzpVersionStr(), a defective array

6.1c23 (29 Nov 2017):
- On Windows with Unicode support, for an archive whose paths used
backslash ("\") directory separators, the backslashes were
mishandled, resulting in extracted file paths/names like "dir_name"
instead of "dir\name". Similar problems could have occurred with
absolute paths in an archive. Both backslash directory separators
and absolute paths violate the standard for zip archives, but they
can be found in some archives. UnZip's policy is to treat backslash
characters as slash characters ("/") for archive members which claim
to originate on FAT (or similar) file systems, but this was failing
in some cases on Windows with Unicode support enabled.

Schniertshauer, SMS]
- On VMS, in -f/--freshen (/FRESHEN) mode, UnZip did not attempt to
create nonexistent files, but it would erroneously create a directory
stack which would lead to a nonexistent file. For example, in an
empty directory (where there's nothing to freshen), when freshening
"a/b/c.txt" UnZip would create "[.a.b]", and then not create "c.txt"
in it. Now, as on other systems, when freshening, neither
directories nor files are created when they do not already exist.
(Exception: When overwriting, or creating a new version of, an
existing file (interactive "[r]ename" option), the user-specified
directories and file are always created.) (vms/vms.c) [SMS]
