Hi all, I've accumulated about 200GB of audiobooks in Apple Books. It's incredibly convenient and works really well in syncing with my iphone, but the problem is that its taking a massive amount of dead space on my startup disk. Does anybody know of an easy way to either migrate that huge library off my startup disk, or even a way to identify where the files are in some kind of logical legible format (books only allows you to delete, there's v little option to manage files), or an alternative software where the transition process isn't too tricky?
