Gah, over this weekend somehow- Someone completely deleted a folder I had containing a lot of things I kinda need. The biggest of which, was some art I did in photoshop that was going into my art portfolio for college. Now, I know I have done it before- its system restore that will revert everything back to an earlier date right? Could someone tell me how to work it, because I just cant seem to find it anymore. I just want my folder back!! thanks guys.
