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.

for data.7z.001 it's ok but for data.7z.002 Error: Can not open file as archive – heisen Dec 21 '16 at 18:08
such that the output : data.7z.001 : 7-zip archive data, version 0.4 data.7z.002 : data – heisen Dec 21 '16 at 18:15

I continued getting an "Unknown format" error until doing the following:

7z e file.7z.001 -tsplit

This worked for me, thank you! Option x supports full path. Option e for only names (as in your example). Option t is for testing. – Rutrus Feb 09 '21 at 18:45
Fixed that. Thanks for the catch! – ryanjdillon Feb 10 '21 at 20:07

For SEO’s sake : I got Open ERROR: Can not open the file as [7z] archive ERRORS: Unexpected end of archive Can't open as archive: 1 without -tsplit, worked like a charm with -tsplit. – Skippy le Grand Gourou Feb 09 '22 at 08:58

-tsplit means type split instead of type 7z. this has the same effect as cat archive.7z.* > archive.7z = the archive.7z.001 archive.7z.002 archive.7z.003 ... parts are concatted to one archive.7z file, because 7z cannot extract from stdin. but this still fails to extract an incomplete 7z archive – milahu May 23 '24 at 17:55
