If the archive contains multiple files, determine which one is corrupted by either extracting them individually until you find the bad one, or by extracting them all and viewing the error log when you are invited to do so. If your archive is a self-extracting WinZip EXE file, open it via the WinZip interface using the Open command and choosing Files of type: / Archives and exe files. If you have a straight ZIP file, open it through WinZip. The idea is to play a trick on WinZip to get hold of the corrupted file through the back door before WinZip kills it off. If you have a later version of WinZip installed, you might need to temporarily uninstall it before installing the older version. Other early versions will probably work too. WinZip fudge This is my 'guaranteed-or-your-money-back' method that works for all ZIP files and WinZip self-extracting EXEs:īecause later versions of WinZip have changed, the first step is to download an older version and install it, choosing the classic interface rather than the 'wizard'. But the bigger the file and the less reputable its source, the more likely it will contain another error-or the same error again.
If you're lucky it might come through without errors the second time. Re-download the archive If your ZIP or EXE archive arrived via the internet, is still available, and you have the bandwidth and patience, re-download it. This means you can either ignore the errors (if only you can access the corrupted file), or you can try to repair them. Thankfully, most of these tiny mutations aren't critical, perhaps affecting the hue of a single pixel in some obscure help screen buried where you'll never notice it. who needs a reason? Stuff happens to perfectly good files sitting on hard drives or optical disks minding their own business, let alone those ricocheting through cyberspace. Computer gremlins, cosmic rays, Mercury in retrograde. Glitches that occur while downloading or copying files can damage them.
I downloaded a big ZIP self-extracting archive (SFX EXE), but when I tried to extract it I got a CRC (cyclic redundancy check) error on one of the files it contained, and I could not access this file at all. CRC error in zip or self-extracting archive
