Lock Box

Probably one of the biggest annoyances I used to face is when I tried to delete a file and got an error that the file was in use. I would go through Task Manager and other programs but couldn't figure out why the file was locked.

I say used to face because once I installed the free Unlocker program, the problems were easy to fix. I know can not only see which programs are using a file, but can unlock or delete the file right away. Probably one of the most important programs in my toolbox.
