First of all, so far a great job Steven.
So i tried anything out and can now say that my ZEN Style 100 MP3-Player himself creats a other form of .m3u playlists.
e.g.
\MUSIC\KINGSO~1\AHASHA~1\02-KIN~1.MP3
\MUSIC\KINGSO~1\AHASHA~1\06-THE~1.MP3
\MUSIC\KINGSO~1\BECAUS~1\02-CHA~1.MP3
\MUSIC\KINGSO~1\BECAUS~1\03-ONC~1.MP3
\MUSIC\KINGSO~1\BECAUS~1\04-MCF~1.MP3
\MUSIC\KINGSO~1\BECAUS~1\08-RAG~1.MP3
which i can also play with MB, directly form the player.
A playlist created with MB says by the same folder structure
e.g.
#EXTM3U
#EXTINF:145,King Of The Rodeo
\Music\Kings Of Leon\Aha Shake Heartbreak\02 - King Of The Rodeo.mp3
#EXTINF:176,Charmer
\Music\Kings Of Leon\Because Of The Times\02 - Charmer.mp3
#EXTINF:201,On Call
\Music\Kings Of Leon\Because Of The Times\03 - On Call.mp3
#EXTINF:189,McFearless
\Music\Kings Of Leon\Because Of The Times\04 - McFearless.mp3
The Player doesn't find any titles in both possible playlist formats.
Do you see any opportunity for me to create such playlist's?
