SFV Files SFV stands for Simple File Validator and is used to check files if they became corrupt after transfer. It does this by doing a CRC (cyclic redundancy check). The poster generates this (text) file with a SFV-generator and the downloader checks it with a SFV-program to see if there are any problems. After the check it displays which files contain CRC-errors and therefore are corrupt. Make a folder on your desktop and use WinRAR http://www.download.com/3000-2250-10007677.html to extract them to this new folder, from there it will eithere make a .bin and .cue file or make an ISO image.
