Organize playlists in folders in Apple Music on Windows
To help you organize your songs and music videos, you can create folders, then add playlists and other folders to them. (You can’t add individual songs or videos directly to a folder.)
Go to the Apple Music app on your Windows device.
Select next to Playlists in the sidebar, then choose New Playlist Folder.
Type a name for the folder and press Enter.
To rename a folder, double-click or double-tap it and type the new name.
To add items to the folder, do one of the following:
Drag playlists or other folders into the folder.
Select the playlist or other folder in the sidebar, select for the item on the right, choose Move Playlist, then choose the folder.
If you delete a folder, all the playlists and folders inside that folder are deleted; however, the songs in the playlist or folder remain in your music library and on your computer.
