I'm very grateful for this. It all works perfectly as set out - on my new Note 3. Files to and fro of all types. Reminds me of an ancient System 7
or thereabouts application called "Apple File exchange" you used to have to use to deal with loading fonts into the system.
Tested all sorts of data every which way both to/from phone and to/from MicroSD card, created my own directories on the card and everything. The Mac certainly can't read that card in a card reader.
So now how do I back up the entire phone - everything - to a Mac drive?
