Can't empty trash
Downloaded a Power Point presentation. Once done I placed in the trash can.When I went to empty the trash a pop up says "can't empty trash because the item (xxxxx).pps is in use. Quit everything but still shows the same pop up.Moved it to a large back up disk,(external), but didn't move, it copied it, now I have to items that can't be deleted because they are in use.
I'm using a 2008 desktop iMac with OS X 10.7.5
What can I do to get rid of this item?
IBook G4, Mac OS X (10.5.8), iMac
