Only that in the cases that came up last time, everyone reported problems
with with 0-length files in .tar format (ditto .tgz) under WinZip, but
nobody reported problems with 0-length files in .zip format under WinZip.
Several inquiries (from me) to WinZip tech support got no response.  A bug
with restoring empty *folders* was documented as fixed in WinZip 6.3.
