I'm setting up a Sonos music player in my house. When using a NAS it requires you point it at a "Share" on the NAS. From what I understand, a NAS can only have a share at the root level. I have numerous other things on the NAS that I don't need shared with the music player. Can I create a share at a different level? Can I create a seperate share at the root level? Any help is appreciated!
