I have a zip (-fzip) archive named: test.z12
On the command line when using:
7z x test.z12
I get:
ERRORS:
Missing volume : test.zip
In spite of this message and the fatal error return code of 7z the file is actually properly extracted
This happens for all extensions "z##" where # stands for a number.
With on exception: z00 works and also all other extensions starting with z like "zap" ...
Looks like a bug to me or do I miss something?
I see this in version 16.02 and 21-01 alpha on linux 64bit.
It happens also on windows in Version 16
Any workaround other than copying the file and renaming it or ignoring the return code?
If you would like to refer to this comment somewhere else in this project, copy and paste the following link:
I have no influence on that name. And it's an automatic process. So I guess I'll have to copy the file to some place with write access and rename it for extraction. Thanks anyway.

zip supports multivolume:
z01
z02
z03
z12
zip
So if 7-zip sees z12 extension, 7-zip expects that it's only part 12 of multivolume archive. And it tries to open main volume that have zip extension.

Ah, I see, thanks a lot.
Is there a way (a switch) to turn that multivolume interpretation off?
No way to switch it off.
You can think why you have z12 exteanion instead of zip.
Maybe you should fix it in another level.
