It is perfect for complex remote operations and almost as powerful as most standalone GUI remote clients.</para> </listitem> <listitem> <para> <link linkend="archives">Archive VFS</link>: allows to browse archives in VFS as it was a directory (ace, arj, bzip2, deb, gzip, iso, lha, rar, rpm, tar, zip and 7-zip).</para> </listitem> <listitem> <para> <link linkend="archives">Search VFS</link>: <guibutton>Feed to listbox</guibutton> places the search results in VFS.</para> </listitem> <listitem> <para> <link linkend="synchronizer">Synchronizer VFS</link>: places the synchronizer results in VFS.</para> </listitem> </itemizedlist> <para>Actions you perform on the files in VFS are performed on the 'real' files. You do not just delete files from the VFS - you delete them from your hard drive. Limitations: you cannot create directories inside a VFS.</para> <para>It is possible to keep the directory structure when doing a copy from a virtual folder to a non virtual folder, by selecting the "Keep virtual directory structure" check box of the copy dialog. Imagine the following virtual folder: <screen><prompt>$</prompt> <userinput>file:/home/myhome/mydir1/myfile1</userinput></screen> <screen><prompt>$</prompt> <userinput>file:/home/myhome/mydir1/myfile2</userinput></screen> <screen><prompt>$</prompt> <userinput>file:/home/myhome/mydir2/myfile3</userinput></screen> Then do the following steps:</para> <itemizedlist> <listitem> <para>go to the virtual folder and select the files</para> </listitem> <listitem> <para>select a destination folder (non virtual!)</para> </listitem> <listitem> <para>press <keycap>F5</keycap>-> copy dialog appears</para> </listitem> <listitem> <para>Check <guilabel>Keep virtual directory structure</guilabel></para> </listitem> <listitem> <para>Select <filename>/home/myhome/</filename> for base &URL;</para> </listitem> <listitem> <para>Start copy by pressing OK</para> </listitem> </itemizedlist> <para>The result will be: <screen><prompt>$</prompt> <userinput>destinationdir/mydir1/myfile1</userinput></screen> <screen><prompt>$</prompt> <userinput>destinationdir/mydir1/myfile2</userinput></screen> <screen><prompt>$</prompt> <userinput>destinationdir/mydir2/myfile3</userinput></screen> </para> </sect1>
