Audiobooks are now found in Books in Catalina, which makes sense. Except I have a massive audiobook collection, over a terabyte worth of data. I don't keep this on my SSD in my MacBook Pro, but on an external drive. No problem with iTunes—just gotta make sure the external drive is plugged in so it finds the files. But with Catalina, it went to "move" my audiobooks to Books and gave me the error that there's not enough disc space. If I drag my audiobooks into Books, I'm assuming it's going to copy the files to a folder on my SSD, not just create a link to the file on the external drive like iTunes did. I see no option in preferences, again like iTunes had, to disable copying the actual file. Anyone played around with audiobooks to see how this works? And can I assume syncing audiobooks via Finder pulls that data from books? It's not just magically searching my drives for .m4b files, presumably. Thanks for any insight!
