Mark all files, move from right tab to left tab, use Context menu, Extract...
Very Strange. I do not get it to show extra files.
I select files and show context menu and do unpack (it shows same unpack dialog as File Menu > Unpack
unpacking a rar with 5 files it say 5 of 5.. and one with 1 files is 1 of 1, and selecting them both and I get 6 of 6
Edit: Ok I think I been able to repo it.. I don't get it everything..
