So I have a zip archive which actually contains a couple of zip archives within it. When I tried to extract the main zip archive I got the error message that there was a checksum error and that one of the zip files was corrupt. I am using winrar evaluation version. I saw there is a way to repair the corrupt file which I did, I selected the main zip archive and repaired that, then i went to the repaired main zip archive and tried to extract it but then i got the same error message saying that one of the zip archives contained in the main zip archive is corrupt, but since the sub-zip archive hasn't been extracted yet i'm not sure how I would repair them, winrar doesn't give me that option it only gave me the option to repair the main zip archive. So does anyone know how I can go about trying to repair that zip archive which is contained in the main zip archive. Preferably with a free program.
