Play Order Using Folder Mode

Using FOLDER MODE, the Clip Jam (and Clip Sports) play audio files according the chronological order they were added to the player (and to the micro SD card). The free software Fat Sorter 1.0.4 will sort the contents of your player  (or any subdirectory) or your micro SD card in alphabetical order (based on the filename; not the data in the ID3 tag).
