is there a program that repairs corrupt archives or zips.
In a word NO.
If however the file (zip) is corrupt only in junk added after the original was created a command line utility called pkzipfix.exe could possibly recover it.
sometimes if you downloaded a file it’s corrupt then you have to download it again.
Sometimes in the middle of a download it stops and the file is corrupted. I got it when i downloaded gta2 sometimes i tried a file 3 to 4 times can somebody help with this?
