Issue: How to fix The action cannot be completed because the file is open in another program?

Hello, I have an issue with a PDF file that cannot be opened nor deleted. I try to delete them from the particular folder, and the window named File In Use appears with “The action cannot be completed because the file is open in another program” message. But all the possible programs are closed. I even tried to restart the PC and delete them before opening anything. It repeats all the time.
