Moving files from external hard drive via usb to Roon ibternal SSD drive

**Nucleus Plus -just purchased. I have installed an internal SSD drive in my new Nucleus +. I have plugged in an external drive with music files on it. Nucleus read and plays them, etc. But I want to move them onto the internal drive an can’t figure out how to do it.
