Zip: Folders within archive cannot be renamed unless they are empty

I would like to be able to rename folders in zip archives. Is there no way to allow this in DirectoryOpus? When I try I get an error message saying that folders within the archive cannot be renamed unless they are empty.

It could say "In order to rename a folder in the archive, the archive has to be completely unpacked and re-packed, is this ok?" or some such.
