this post is old, but I have the same problem. my filename is a different random fileneme (3590F75ABA9E485486C100C1A9D4FF06GFQGDUHIMHWKCSQA), and my system rebooted in the middle of a wipe. Now, it won't let me delete the file, says access denied. I'm an administrator on the box, still doesn't let me. if I try to rename it move it or anything it says it's in use by System.
