How to Repair a Broken ZIP File
ZIP files compress data in order for a file to take up less space on a computer. This helps users save memory space after downloading a large file. Unfortunately, ZIP files can become corrupted to the point where you cannot access them. Fixing corrupted ZIP files is not a difficult task, but it does require a user to have Administrative access to the computer.
