Thank you, than i have at least not to redo, just edit them after copying.

You can copy and paste and this includes any sub-playlists, however when using Criteria Playlist is it will point to a specific Playlist file. So this isn't to the newly copied Playlists.

Is it possible to completely clone a multi-level playlist structure?

I have an auto playlist (all songs with a rating >= 3), then below nodes/playlists for various genres, then again below for decades. every node based on "parent playlist" and additional filters. Can this construct be copied completely, or does the tree have to be recreated manually?
