Sometimes when I follow the process to safely remove a USB flash drive, I get told that I can't remove the drive because some programs are using it. However I'm unable to tell which programs these are, so I end up having to close programs - sometimes even randomly.
How do I find out which program is using my USB flash drive?
I've searched the Internet but have found nothing promising; one solution might be via Process Explorer since it shows handles, but I don't know how to use it to solve my problem.
The best solution would be to have a program that can automatically close these programs for me, or at least tell me which programs these are.
