Organize playlists into folders
To help you organize your songs, videos, and other items, you can create folders, then add playlists and other folders to them. (You can’t add individual songs or videos directly to a folder.)
Create a folder
Choose File > New > Playlist Folder.
Type a name for the folder and press Return.
Drag playlists or other folders into the folder you just created, or drag the folder into another folder.
To move a folder out of another folder, drag it to the left edge of the iTunes window.
To rename a folder, double-click it and type the new name.
