Yep, I’ve found a good app to add to my “Mr. Fixit” toolbox (thanks to TheWindowsClub and Anand@TWC).
A zipped file is highly structured one and therefore prone to corruption from defragging, etc. Your usual zip utility won’t work with the file as it’s damaged structure prevents the utility from working.
“This is because all zip tools check archives for integrity. If CRC values of the original files of an archive don't match the extracted ones, the standard tools won't extract them. In such a case DiskInternals ZIP Repair helps repair zip structure and extract the contents of the archive. Full automation of the recovery and a wizard-like interface make zip repair no more than a snap.”
- DiskInternals
The real plus of the utility is the Wizard interface which really makes things easy. There are other tools to do the same thing, but they lack the interface ease do I’m recommending the easiest one to work with. Hopefully, this will help you prevent data loss.
