How can I identify what application is using the file?

Often when I try to eject my external USB hard disk, I get this message:

Problem Ejecting USB Mass Storage Device

This device is currently in use. Close any programs or windows that might be using the device, and then try again.

How do I find out what the device in currently in use by?

(I’ve already tried Unlocker, it always says “No locking handle found.”)

Process Explorer should work. just hit Ctrl+F and type in the name of the file. It should show all programs that are using that file.
