I met a file that wasn't there...

Cleaning up some files on my Windows desktop,I saw a blank .torrent icon. So I attempted to delete it. Instead of the usual trip to the recycle bin,I got a message that said the file no longer existed. After attempting to do this in both safe mode and through Command Prompt,I pulled up Google Search and ran the error message through it. I got a link to this freeware program called Unlocker which instantly did the trick. It's also a good thing if for some reason a file is not released after it's associated program is closed. I recommend it as a satisfied customer.
