The most important thing when trying to recover any deleted file is to limit your use of the hard drive. Do as little as possible on your PC until the files are recovered, as usage of the drive will overwrite some of the files, making them unrecoverable. Do not install/add anything new to your PC. If possible, run an undelete tool from your FD or CD. Follow the above suggestions and hopefully you can recover most, if not all of the files.
