I think it may be possible to accomplish the requirements of new member Flunky with the quick execution of a simple batch file command directly inside a subfolder of Music in the player or the micro SD card.
For example, in Flunky’s Clip Sport there can be a subdirectory named “Beethoven”. And this subdirectory contains all the 32 folders (each with 3 or 4 audio files). And when Flunky uses Windows File Explorer to view this subdirectory collection, all 32 folders are properly named so they are displayed in the exact desired order of playback. (And the internal 3 or 4 audio files can be displayed in the desired order.)
Then Flunky can create this simple 2-line text file (using Notepad) and save it as “Playlist.bat” in the Beethoven subdirectory.
@echo off
dir /o:n /s /b *.mp3 *.wma *.wav> Beethoven.m3u
Then use Windows File Explorer to double-click on the bat file and the Beethoven.m3u file will be automatically created within 3 secs or less. Then use Playlists mode from the MUSIC menu or the CARD menu to start your playback. Make sure all the possible shuffle commands are set to “Off” for your desired linear playback.
If you decide to repeat this process with other subfolder collections, make sure you use different names for the “m3u” files
