Since I apparently have nothing better to do, a small lecture about something called file permissions.
Files on computers have something called file permissions. These permission control what users/programs are allowed to delete what. When a particular file has permissions that prevent a program from deleting it, that program cannot delete it. That is why some files in your My Documents were not deleted.
But from the tone of your posts, I can tell that you aren't here to learn, just to find someone to blame. So this post is entirely wasted.
