When you can't open, edit, or delete a file in Windows File Explorer, it's either still open in a program running in the background or something didn't close properly.

If you receive File in Use. The action can't be completed because the file is open in another program even if file is closed in another program, see this.

To do this: Press Windows key + R on your keyboard to open RUN dialog box. At RUN dialog box, type “sysdm.cpl” and press Enter or click OK to open System Properties.
