Nice try...the previous owner could not have deleted it. That folder is protected. I bet you're in My Documents. Hit the "Up" text at the bottom left of screen and that should take you back to My Device. And you shoulda done a hard reset right when you got the phone to clear out all data. To do that you can go to Start>Programs>ClearStorage and follow the instructions on then screen. Like weedahoe said it's gonna be long thread.
