Q: Where can I find Volume number, like "Details: RAR 5, volume 483"

[sanderjo]

Short question:

How can retrieve the Volume number of a specific rar file, like Details: RAR 5, volume 483 as reported by "rar l <rarfile".
I need this for obfuscated rar files of which the file name is unknown.

I can't find it in https://python-unrar.readthedocs.io/en/v0.3/rarfile.html

EDIT:
I checked the unrar source code, and I think this line in list.cpp prints it:

mprintf(St(MVolumeNumber),Arc.VolNumber+1);

So official name would then be VolNumber.

$ unrar l blabla-nothinghere.rar
