The only other thing I've been told can work is to disable any anti-virus you have running, do the above sequence of steps, and re-enable your anti-virus. Which OS are you using? Files 2 Folder has been developed and tested to work on Windows 7. I've received reports from users of Windows 8 and Windows 10 that they were able to get it to work, though. That said, I cannot support those operating systems as I do not own them.
