you may want to try PKZip, as it can recover 'damaged' zip files, i'm not sure how far this extends to the corrupted files and such, but i've used it before on 'corrupt / damaged' zip files with some success.

if you are using a fat32 partition (god help you if you are), you may want to try something called 'disk investigator', its free and can recover stuff from fat32 partitions, therefore if your zip file is stuffed, you may be able to recover the files fro the hard drive. **remember that when you recover stuff from a hard disk / floppy etc, that you recover it to a **different** disk altogether, otherwise you risk overwriting the stuff youre trying to get back**
