Batch File Needed - within 3 days

Hi! I am not sure if you are able to do this but ... I would like to get a script made that automatically deletes (compeletly deletes) PDF files in a folder on my desktop after 10 mintues automatically. It must automatically start when the computer is turned on and has to work on windows xp + Also the program has to execute only once a file has been added to the folder (It usually will only have 1 file in the folder). I ask that because I might add a file to the folder on 9min 59seconds and it will delete before I can upload that file. I need this done within the next three days. Thanks
