Downloaded opened Zip file will not delete

I just downloaded Star Trek ride by poppy uploaded 7/4. The desktop file will not delete. The folder that had the track and object files in after unzipping the download. I get a message that says this folder is in use by another person.

Anyone know how I can get this empty icon file deleted?

First of all, which operating system are you using?

Windows XP Service Pack 3. Sorry I didn't mention it. Off work not feeling well.

Oh, well, I would try to restart the computer and try it again

Close the program that you were using. Close winrar, or winzip and voila, problem solved. That happens to me often. Deleting .doc files when having MS or OO open. Also happens when trying to delete nltracks when having NL open, etc.

^or do that

Restart worked. Thanks though for your responses. Can this thread be deleted or closed?
