  <para>A basic 
  <link linkend="features">OFM feature</link> is VFS, this an
  abstracted layer over all kinds of archived information (ZIP
  files, FTP servers, TAR archives, NFS filesystems, SAMBA shares,
  ISO cd/dvd images, RPM catalogs, etc.), which allows the user to
  access all the information in these divergent types of
  filesystems transparently - just like entering an ordinary
  sub-directory. &krusader; supports several virtual
  file systems: 
  <itemizedlist>
    <listitem>
      <para>
      <link linkend="remote-connections">Remote connections
      VFS</link>: provides the capability of working with a remote
      connection session (FTP, NFS, Samba, FISH, SFTP) like with
      local filesystems. 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>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
  ca not create directories inside a VFS.</para>
  <para>It is possible to keep the directory structure when doing a
  from 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>$</prompt> <userinput>file:/home/myhome/mydir2/myfile3</userinput></screen>
  Then do the following steps: 
  <itemizedlist>
    <listitem>
      <para>go to the virtual folder and select the files</para>
    </listitem>
    <listitem>
      <para>select a destination folder (non virtual!)</para>
    </listitem>
    <listitem>
      <para>press 
      <keycap>F5</keycap>-&gt; copy dialog
      appears</para>
    </listitem>
    <listitem>
      <para>Check 
      <guilabel>Keep virtual directory structure</guilabel></para>
    </listitem>
    <listitem>
      <para>Select 
      <filename>/home/myhome/</filename> for base
      &URL;</para>
    </listitem>
    <listitem>
      <para>Start copy by pressing OK</para>
    </listitem>
  </itemizedlist>The result will be: 
  <screen><prompt>$</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>
