I downloaded "OLC's Video Tutorials"
Then exported then to a file in "my documents" using Winzip
"Video Tutorial Supplement for OLC 'Gold'.avi" played perfectly on windows media player.
"Original OLC GUI Video Tutroial.avi" only played the sound.

I therefore attempted to delete them inorder to redownload them.
Each time I try to delete them I get the message:-

Cannot delete OLC's Video Tutorials.rar: it is being used by another person or program. Close any programs that might be using the file and try later.

If when I get this error message I press ctrl-alt-delete then the only programs listed as running is windows explorer. I do not know how to stop the program that is stopping me from deleting these files.

I have since been able to delete "Original OLC GUI Video Tutroial.avi"
but I cannot delete "Video Tutorial Supplement for OLC 'Gold'.avi"

Now when I double click on "Video Tutorial Supplement for OLC 'Gold'.avi" it opens windows media player and playes the video but also brings up a second error message:-
Windows Explorer has encountered a problem and needs to close......Send error report.
It then either closes windows explorer, or closes it and my computer showes only my desk top pictire without the program short-cuts and without the start bar at the bottom.

Please help me.
How can I get rid of these downloads.


I also tried removing from my computer my instalation of winzip, and a few other downloaded programs that I do not use, but I could still not delete these video tutorials.
