Repair Corrupt or Partially Damaged ZIP Archives

While it is a good way to reduce the size of your files, sometimes you may find the zip file you've downloaded can't be opened because of some error such as CRC errors. Depending on how bad the damage is, you may be able to recover some of your damaged archives using Object Fix Zip. Like the maker says:

"This software is designed for testing, fixing and processing of corrupt or unusable ZIP archive files that are partially damaged or not completely downloaded"

To save time, it allows you to recover multiple damaged zip files at once. The original archives won't be modified if you choose to save the result of the recovery attempt as new archives.

It is free, can be operated under Windows Vista, XP, 2003, 2000, NT, Me, 98, 95, and can be downloaded from here.
