Can Windows tell me what is using my USB drive?
I'd like to unplug my USB mass storage device, but I get the following error message from Windows:
Windows can't stop your 'XYZ' device because it is in use. Close any programs or windows that might be using the device, and then try again later.
How can I find out which application locks the device, so I can safely unplug it without having to close all running applications first?
Note: I'm working on a Windows Vista system.
