<H1>-t (set Type of archive) switch</H1>
<P>Specifies the type of archive.</P>
<H4>Syntax</H4>
<PRE class="syntax">
-t{archive_type}
</PRE>
<DL>
<DT>{archive_type}</DT>
<DD>Specifies the type of archive. It can be: *, 7z, split, zip, gzip, bzip2, tar, ... , or
combination of them, like: mbr.vhd
</DD>
</DL>
<P>If -t{archive_type} switch is not specified, 7-Zip uses extension of archive filename to
detect the type of archive. If you create new archive, -t{archive_type} switch is not
specified and there is no extension of archive, 7-Zip will create .7z archive.</P>
<P>When you extract archive of some types that contains another
archive without compression (for example, MBR in VHD), 7-Zip can open both
levels in one step. If you want to open/extract just top
level archive, use <SPAN class="filename">-t*</SPAN> switch.</P>
<P>Note: gzip or bzip2 formats support only one file per archive.
If you want to compress more than one file to these formats,
create a tar archive first, and then compress it with your selected format.</P>
<H4>Example</H4>
<PRE class="example">
7z a -tzip archive.zip *.txt
</PRE>
<P>adds all <SPAN class="filename">*.txt</SPAN> files from current directory
to zip archive <SPAN class="filename">archive.zip</SPAN>.</P>
<PRE class="example">
7z t -t7z.split archive.7z.001
</PRE>
<P>tests all files in <SPAN class="filename">archive.7z.001</SPAN>. It also checks
that archive is multivolume .7z archive.</P>
<PRE class="example">
7z x -tiso archive.iso
</PRE>
<P>extracts files from <SPAN class="filename">archive.iso</SPAN> open as ISO archive.
<PRE class="example">
7z x -tudf archive.iso
</PRE>
<P>extracts files from <SPAN class="filename">archive.iso</SPAN> open as UDF archive.
