I copied some movies onto my computer and now i cant delete them, every time i to it says "Cannot delete the file, it is being used by another program" or something like that. How can i get rid of these files?

Instead, download and install http://www.techspot.com/downlo.....ocker.html Unlocker Assistant. This will automatically fire-up when some file is locked up and shows a list of processes that is holding it down. U get the option of killing those processes to delete the file, rename the file, move etc. Pretty nifty tool.

if you have p2p'd these files also make sure your p2p program isn't sharing with someone else if so terminate the D/L then try deleting the files.

someone might be trying to download it from you.
