Recover healthy files from damaged zip and sfx archives with Zip2Fix
Zip2Fix is a small, free and portable tool that will let you extract healthy files from a damaged zip archive, when your regular zip archiver / extractor cannot process an archive at all, because some of the files included in it are useless and cannot be extracted.
All good files will be extracted and immediately and included in a new zip archive.
Zip2Fix works also with sfx (self-extracted) archives. Unfortunately it does not support rar or other archive formats.
The program is reliable and fast, but it doesn’t support drag and drop; you have to browse to the archive you need to fix or paste its address at the “Open” dialogue.
