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.
