5. Navigate to the file location of your corrupted zip file;
6. Write* “C:\Program Files\WinZip\wzzip” -yf zipfile.zip and press the “Enter” key;

*Please Note: The content between the double quotes is referring to the exact installation location of your WinZip program. Likewise, change “zipfile.zip” with the name of the file you want to recover. Last thing, don’t forget to use double quotes. You need them because the space between “Program” and “Files” in the “Program Files” phrase. Otherwise you’ll be displayed an error. Furthermore, if you want to recover a split or spanned Zip File, you need to type this command line instead of the one suggested at step 6: << “C:\Program Files\WinZip\wzzip” -yfs zipfiles.zip >>

WZZIP is using the original zip file to read data which will be saved in a new file having a fixed suffix in its name. None of the data contained in the original zip file will be modified in any way.

Using WZZIP will repair the zip file structure without changing the data itself. However, if the contained data is corrupted, of it has a CRC (cyclic redundancy check) error which is usually detected when extracting files, the new archive created using WZZIP will also be corrupted even though the data structure might be fixed this time, because data integrity cannot be fixed by restructuring it.
