7zip cannot unpack tar archive created by "git archive". Apparently there are some differences.
The reason I'm asking is that I would like to be able to unpack tar archive from git on Windows and 7zip is great utility. Is there some flag/workaround (short of unpacking tar archive created by git and packing it with GNU tar).
7zip
and what is the command you are using for extraction?
