I've had enough of trying to rename/move/delete a file and getting the message: "source or destination file may be in use"

For those of you who regularly have this problem, I've found this handy little program called Who Lock Me. All it really does is, when you right click on a file and select the "Who Lock Me" option, it tells you which programs are currently using that file. This is the best solution I've found so far for this problem, short of a reboot which for some of us takes quite some time. You can even install this without rebooting
