Listening to own audiobook files on iPad mini
I have a number of m4a and m4b audio files, mostly course lectures, on a NAS drive connected to my desktop system. I would like to copy some of them to my iPad mini and listen to them there.
I understand I will need a wireless connection to headphones; I can probably figure that out.
But how to copy the files to the iPad and then to play them?
Would appreciate pointer to help files or other info on this.
P.S. I do this all the time on my iPod Classic; but the interface looks way different.
