I tried to extract a ZIP file I was send this afternoon and got the following error with unzip…
Archive: ARCHIVE.zip skipping: ARCHIVE.zip need PK compat. v4.5 (can do v2.1)
Turns out this means it was compressed with a newer version of PKZIP to what unzip can handle, but p7zip can take care of it.
Grab the latest build, then do the usual building and all is good. Sounds like a commercial for a construction company.
% make # make install % 7za x [ARCHIVE.ZIP]
