How to add PDF-booklet to album
I made a PDF-file as booklet to add it to my music album. But I found it in the "books" directory on my Win7 PC (sub-directory to audiothek). Because I don't find books section in iTunes 12.9.4.102 I can't change the file settings from book to music as I did years before. How do I manage to add booklets directly below the music files like with other albums I own?
