First thing to do is stop using the computer immediately. The more you use it, the better the chances of parts of the files being overwritten. Then from another computer try a program such as Recuva. If that doesn't do it, you'll have to decide if the files are worth a not insignificant amount of money for professional recovery services.
My roommate mistakenly deleted a folder that held many movies off from my Windows 7 partition. There was no another copy of all these connected movies and I also could not find them in Recycle Bin. Is there any way to restore them back? I have connected these movies for a really long time and don't want to spend more to find them back again. Thanks for any advice!
