Can't copy files between devices

I get an "Acces denied" every time I try to copy directories or files from a thumb driv to my hard drive. How do I undo this problem?

Do you get the same error in other programs?

If so, the error is unrelated to Opus.

If not, the error is probably caused by something blocking Opus from reading the thumb drive or that type of file (or file contents); most likely antivirus or privacy software.

(Running Opus elevated can also cause problems, if you're doing that. Use the UAC support built-into Opus instead of launching the whole program elevated, if that's the case.)
