To me, it sounds like what you are trying to say is you have a corrupt
file. Even unzip does not like it. It sounds as if the corruption is in
the zip definition part. Possibly the save was interrupted before the
write was completed. In this explaination i may or may not be correct.

If i am, does anyone have any experience in unzipping corrupt zip
files, or know of any utility for such a purpose?
