Backing Up Music Files - HDD External

There is no File Copy function in Roon OS. A ROCK/NUC system is a music appliance, not a general purpose computer.

Hi, I just posted another topic on this because it’s still causing a major pain. I have a new MacBook Pro that can read ExFat, but my question is what software can one use for the backup as opposed to just drag & drop which ultimately doesn’t work?
