Why the double post? You posted this question in the Computer Help Forum also. Someone is there trying to help you. Double posts only confuse things. Here is the link to the other thread.
I am using WinXP pro, recently I copied an .avi file on my hard disk since then I am unable to delete it which is very strange & I do not know why. Every time I try to delete it I receive a worning message saying :" can not delete the file... it is being used by another program. Close any program that might be using it & try again" . Up to my knowledge there is no other program using this file,& when I am pressing the control+alt+delete it showes no program running. I scanned the computer for viruses or spy wares & I found nothing.
It is very annoying to see this file & can not be deleted,
Any help would be highly appreciated
