It would help if you tell what tablet you use and what "playback system" on that tablet.
Let me guess (without looking at your earlier post): it's a Windows 8 Pro tablet and your player is Windows Mediaplayer 12. But i might be wrong.
OK... So now I've got a number of music files transferred to my External SD Card. I can click on the first file and it plays OK but when that track is finished, I have to select the next track to make it play.....
My Question, is there any way I can configure the playback system so that it will play all the tracks in order, without having to select each one?
