After you have edited your GTA IV files, you start the game and it crashes. Then you realize that you forgot to make a backup. Normally, you now have to reinstall the game!
With this tool, you can easily recover the original files:
1. Select your GTAIV Directory / or a temp directory (for example an empty folder) 2. Select your DVD-ROM Drive 3. Choose a file you want to recover or use a scriptfile 4. Click 'Recover' and wait a few seconds/minutes (you will be asked to insert the disc 1 or 2 into your drive) 5. The file has been recovered and the game can be started (or modded) again
