I downloaded a series of packages that all compress one thing. The files end in .0, .1, .2, etc.

The User Lists of these packages I downloaded say to use the file.bat to successfully extract, or to use 7zip. I do not understand how to do that with 7zip.

If you don't see Extract Here in the popup menu - please try the command-line solution from the answer below – Sergey May 11 '12 at 0:35

Install 7zip from the Ubuntu Software Center.

Install via the software center

Command-line solution:

In terminal, cd to the directory that contains the volumes and run 7z command on the first file from the sequence:

cd ~/Downloads
7z e asdf.iso.0

7zip should notice that you have a multi-volume archive and unpack everything.

GUI Solution

  • Right-click the first package of those you downloaded (eg file.zip.001).

  • Select "Extract Here".

Using 7zip to extract iso file is extremely simple even it has multiple parts. Let's assume you have an iso archive with three parts named by a.iso.001, a.iso.002, a.iso.003.

The standard command line is in this way:

7z x a.iso.001 -tiso.split -o output_dir

or

7z x a.iso.001 -tudf.split -o output_dir

Passing the -t flag with the "split" indication will specifically tell 7z that the iso has multi-parts, the preceding "iso" or "udf" will depend on your iso container format.

-tsplit (only) did the trick for me - thanks! It would have been "extremely simple" if 7zip would recognize its own (!) split archives and not force users into diving into the subtleties of additional cmdline parameters. I remember older archivers who were easily capable of that. shrug – JensG May 22 at 8:16
