I’ll be setting up my WD My Cloud PR2100 this weekend. I’ve transfered all my files from my old-n-slow Mac to an external hard drive. I have a new laptop that I’ll be setting up this weekend. So my question is after I set up the Nas will I be able to transfer my music & photos over to Nas using the external hard drive? Or do I need to transfer them from ex hard drive to laptop first? And how does Plex come into play with the transfer?
