To activate Recursive Playback mode the folder icon in the File Browser should be kept pressed for a second or more. After that the player will start playing all audio files in that folder and all sub-folders. The playback will be automatic, recursive and in alphabetical order.
The recursive mode will be saved during system shutdown. It will continue playback from the file at which the system was stopped. To interrupt the Recursive Playback any file/folder should be pressed in a usual way (without holding for 1 sec).
