How to copy a Playlist to a thumb drive

I am hoping that someone can give me some direction with this. I have a server and I have 4 devices that have just been converted to kodi. Each one I have to create a music playlist for each device I have an example I have (4) kodi boxes (1) is the HOUSE, (1) is MASTER BEDROOM, (1) is the FAMILY ROOM (1) is the KIDS ROOM..

I’ve created music playlists on the HOUSE unit and I wanted to copy that playlist to a thumb drive and then move it to the other three kodi units without having to sit down and create the same music playlist on each machine. I have not been able to figure out how to do that or if it’s possible. Each of these four devices are connected to my rack server also. Not really sure if I’m saying it correctly but anyway you could help me or anyone can help you greatly appreciated.

Thanks Steve
