How to get vlc to play through 6 folders

[jimdays]

I have VLC for android 1.7.1 and I have an Audio book that is on six folders, named 11,22,33,44,55,66. Each folder has around 20 mp3 files. Presently, if I am playing the files in any folder, when the file is played through, the next file will start playing.This is good. However, when all the files in a given folder have been played, VLC won't advance to the next folder and continue playing. VLC just stops when all the files in a particular folder have been played. Is there a way to get VLC to continue playing until all the files in all six folders have been played? In other words, I want VLC to advance to the next folder and continue playing all the files in that folder. I have attached two screenshots, first showing the 6 folders and the second is playing a file in one of the folders.

Well, you can use a .m3u (Playlist file), it is a text file located in your
audio book directory ( at the root level).
Then in that file, you set the audiofiles you want to be played
for instance :
11/07 Track 7.mp3
33/Whatever.mp3
44/Album2/Track2.mp3

You may play this file with VLC. Enjoy
