Thread: Next Folder Command

In my old Sony MP3 Deck, music could be organized into folders and traversed incrementally. Say you had some folders like this:

Folder A

Folder A1

Folder A2

Folder B

Folder C

Folder C1

Folder C2

If there were mp3s in Folder A, the deck would start by playing those. Hitting the next album button would play all the songs in A1, followed by A2, followed by B, etc. The previous album button worked the same way, in reverse. Is there a command in RoadRunner that will traverse folders like this?
