Hi, First post, so please be gentle! I have some files I am unable to delete, when I try in Windows Explorer I get "Cannot delete file, it is being used by another person or program." There are no other programs running. I have also tried deleting it via the DOS prompt and get "The process cannot access the file because it is being used by another process". I have rebooted a few times and get the same. It is annoying as the files are hard disk copies of a dvd and are taking up 4+ gb! Any ideas?
