How to extract a zip archive of an OS390 iso disk

 
Edited

Hello
?
I am on Windows 11, and I am looking for a way to extract the OS39RA.A80 file from a ZIP archive consisting of two files OS39RA_1.A80 and OS39RA_2.A80 which are contained in the OS39RA.ZIP archive.
?
I tried with winrar without success. It does not consider it as a multi-file archive.
I also used the unzip program of the iso file, but it does not work because it's a 32bits
?
Thanks in advance

It is not a multi-file archive, it is a DASD image divided into two parts, do you remember the time when PC operating systems could not digest files longer than 2GB?

I can't tell you more. I'm not used to run licensed product with Hercules

Hercules can use those split files out of the box, once they are correctly named. Also, the ckd2cckd64 utility implicitly uses that naming convention when converting files to e. g. cckd64.

Of course, conventions for the P390 support software are different of the ones from Hercules.

:wq! PoC
