@emphrath That Worked Great. Problem solved for file/folder transfers back and forth. But ... I couldn't play any of the videos on the server regardless of their formats (mpg, mts, avi, mp4) using Media Player, Video Player, or UTmedia. Though some of the videos will play if I transfer them to the phone.
On the Nexus 5 that's no big deal, watching a movie on a 4.9" screen is not um ... optimal. But I won't give my Nexus 7 or 9 the Ubuntu Touch treatment if they can't play movies from the server. Where do you suppose the problem lies?
Thanks ... Bob,
