Hello I recently had a problem deleting a file off of my desktop, I typed the error message into my google toolbar and found this forum, I also found another forum where someone posted a link to download a program called unlocker. Here is the link and if anyone has future problems like this, I think this is a great solution because it worked for me.

Just read and find the link that says download the freeware app unlocker.
