Compressing two or more files as a single Zip file enables you to reduce the file size and save storage space. A Zip application like WinZip uses number of compression algorithms to create a .zip file. A Zip file can be corrupted due to file version mismatch, application malfunctioning or incompatibility, malicious software like virus, CRC (Cyclic Redundancy Check) errors and more. In most cases of Zip file corruption, the data saved in the Zip file becomes inaccessible and an error message gets displayed.
