Help with playlists

[Bookbear]

Hello and please bear with me here... this will take a bit to express.  I am using Music Bee on a Windows Ten box with a Sony Walkman DMP.  With my previous computer and DMP, I used a stand alone program called  'Playlist creator' to make playlists in m3u format.

With the new DMP, I am for the first time using Music Bee to create playlists. Almost all of my music is in FLAC format, so the files are larger. I first create the list in MB (m3u format) on my computer, name it, then send it to the device (Sony NW-A35).  This works fine, but.....

Each time I do this, a new folder with the name of the playlist and copies of the music files is created in the memory of the DMP.  That is, I have the original FLAC file of the song in the player's memory PLUS another copy of the song in the newly-created playlist folder. Since the memory is already quite full, playlists will very quickly chew up the remaining memory.

Is this behavior normal?  Shouldn't a playlist simply be a list of locations where the player will find the songs on the playlist, not a duplicate set of the song files?  Or am I misunderstanding how Music Bee handles playlists? 

Thanks in advance for any help or insights you may provide!

Press Ctrl+o, select Devices, select your player, click the Configure button on the right, click on Settings, and uncheck the box for "create a sub-folder for each playlist and its tracks", then click the Save button.

Thanks for the tip.  I deleted the folders that were created in the walkman, verified that the 'Create sub-folder' option in MB's device settings was NOT checked, and sent a new playlist from MB to the Walkman.  I got the same result, a new folder with the name of the playlist as the folder name created in the Walkman, with copies of the songs residing in the new folder as well as in the memory of the player.

Any other ideas?
