I think everyone who has struggled to understand how SanDisk players interpret m3u files will appreciate your effort to obtain and post the link to the SanDisk batch file for automatically compiling m3u Playlists.
I am taking the liberty of pasting the text contents of your cited text file: “Playlist3.bat” here:
@echo off
dir /o:n /b *.mp3 *.wma *.wav> Playlist.m3u
One limitation of this simple method is that it does not allow for a playlist compilation of audio files from several subdirectories. The software “mp3tag” can produce a slightly more complex m3u file that can point to audio files residing in multiple subdirectories inside the main Music directory. The m3u file can be saved into the main Music directory or any subdirectory inside the Music directory.
