Just one point. I THINK that 'Playlist Menu' --> 'Export Mp3s' function Exports
the hidden MP3 files to USB.
And you will then ask what are the hidden MP3 files ! Well i THINK they are produced when using the "Settings>Compression>Select FLAC, FLAC+MP3, MP3-128k, MP3-256k or none (WAV)" is selected.
(this work on your whole HDD music collection and can take hours to work (there may also be bugs!))
To export the music for a playlist I THINK the correct option is "Playlist Menu> Export Playlist
This function writes all the music in a playlist to the drive in USB C. It can take a long time if the playlist is big. Originally intended for transferring smallish collections that you can listen to in the car for example.
HOWEVER, My music is all FLAC compression and my car can not understand this!! BUT if you set your main compression on load or ripping CD to an MP3 option (MP3-128k, MP3-256k) you would be OK.
Hope this helps
Fred.
