What is the "Album Artwork" folder for iTunes 12?
It might sound like a silly question but I'm in the process of setting up a shared media folder for iTunes and so have been checking what is stored where. I don't understand what the "Album Artwork" is used for.
All the music in my library has artwork associated with it. I assume the artwork is added as metadata to the audio files as it shows up in Finder if I browse the media folder.
I'm using iTunes 12.9.5.5 on Mojave and 12.8.2.3 on El Capitan. Both have an "Album Artwork" folder but on El Capitan it has just a few empty subfolders. On Mojave it has more subfolders and a couple of them are populated (the "cache" and "remote" folders).
I stopped using artwork from Apple years ago and add jpg files locally.
