0012   <para>This function splits one (large) file up into multiple
0013   smaller files so that they can be placed on smaller media
0014   (&eg; ZIP drives, ...) or sent by email. The multiple
0015   files can be combined again to recreate the original file.
0016   &krusader; and <trademark class="copyright">Total Commander</trademark> split/combine
0017   functions are compatible. To split a file choose
0018     <menuchoice>
0019       <guimenu>File</guimenu>
0020       <guimenuitem>Split</guimenuitem>
0021     </menuchoice>
0022   or
0023   <keycombo action="simul">&Ctrl;
0024   <keycap>P</keycap></keycombo>: a <guilabel>Split</guilabel> dialog
0025   will open to confirm the operation.</para>
0026   <para>If the name of the original file is
0027   <filename>foo</filename>, then the name of the smaller files will
0028   be
0029   <filename>foo.000 foo.001 foo.002</filename> &etc;
0030   There is no theoretical limit in the number of smaller files, but
0031   it is recommended to limit the number to a maximum of 1023 files.
0032   &krusader; creates a
0033   <filename>foo.crc</filename> file. This file contains the name,
0034   size and the crc checksum of the original file. It is possible to
0035   combine the file without the
0036   <filename>foo.crc</filename> file but in this case
0037   &krusader; cannot check if the original file was
0038   recreated correctly.</para>
0039   <para>An example of a
0040   <filename>foo.crc</filename> file:
0041   <programlisting>filename=foo size=432998467868 crc32=21EB719A</programlisting></para>
0042   <para>To combine the multiple files choose, select a partial file
0043
0044   <filename>foo.xxx</filename> and choose
0045     <menuchoice>
0046       <guimenu>File</guimenu>
0047       <guimenuitem>Combine files...</guimenuitem>
0048     </menuchoice>
0049   or
0050   <keycombo action="simul">&Ctrl;
0051   <keycap>B</keycap></keycombo>. The target folder is the
0052   inactive panel and can be changed. The file names must be
0053   numbered in ascending order:
0054   <filename>foo.001, foo.002, foo.003</filename> &etc; or
0055   have letters in ascending order: ("
0056   <userinput>
0057     <command>split</command>
0058     <option>-b</option>
0059   </userinput>letter method")
0060   <filename>fileaa, fileab, fileac</filename> &etc; If
0061   the file
0062   <filename>foo.crc</filename> is found in the same folder as the
0063   partial files, &krusader; will use this file to check
0064   the combined file for errors.</para>
