Your original command 7z e archive.7z.001 should work (as should all other 7-Zip commands that operate on existing archives). If 7-Zip complains about an obviously existing file archive.7z.002 not being a suitable archive that file must be corrupted (or you just discovered a bug in 7-Zip).

The following warning from the 7-Zip manual about the creation and use of multi-volume archives may be relevant:

Please don't use volumes (and don't copy volumes) before finishing archiving. 7-Zip can change any volume (including first volume) at the end of archiving operation.

(source: /usr/share/doc/p7zip/DOC/MANUAL/cmdline/switches/volume.htm if you installed the p7zip package; I couldn't find an online version of the manual)

7z x data.7z.001

7z like that will find the others automatically (002 003 and so on)

  • it works perfectly for data.7z.001 but for data.7z.002 Error: Can not open file as archive – heisen Dec 21 '16 at 16:52
  • Can you check the size of the files please? It sounds like it wasn't completed right the creating of the zip files. – Adonist Dec 21 '16 at 17:00
  • 104.9 mo for data.7z.001 and 69.7 mo for data.7z.002 – heisen Dec 21 '16 at 17:02
  • Can you give it a try with: – Adonist Dec 21 '16 at 17:10
  • Can you give it a try with: 7zr x data.7z.001 With the 'r' with 7z. Found this option in a few sites but not sure if that will work. – Adonist Dec 21 '16 at 17:11
