Object FIX ZIP clearly justifies its name of fixing faulty zip files.
    Files extracted from zipped files could have errors. Files could be corrupt or partially damaged. These problems could be fixed using this powerful program. Zip files specified to be repaired can be repaired and reconstructed. Zip archive files can be rebuilt freshly without errors using this software. It supports all zip files built using PkZIP and WinZIP archiving software. The process of repairing these files is made extremely simple using the wizard-driven interface. You can add all zip files needing repair using simple mouse clicks. Encrypted zip files can be processed by specifying the password later when asked. You just need to specify the action to perform on the selected files and it is done within minutes.
