I downloaded a file related to an AutoCAD trial offer some time ago, but never got around to doing anything with it.
Last week, I tried deleting it, but got the message "this file cannot be deleted it is being used by another program" etc etc...I just left it alone, thinking it'd be okay to delete some other time.
Well, I was wrong, I tried deleting it again today but got the same message...I have absolutely no clue what program is using this file, as there doesn't appear to be anything running that even remotely relates to AutoCAD....
How can I find out what program/process is using this file? I am upset now, I want this damn thing gone.
