Getting books from Finder into Kindle
I'm restoring a new phone. I'll leave aside how really bad the process software is, and get to the problem. On my previous phone I had a bunch of books, 30 or so, that were in the Finder in Files under Kindle. I could add books there, and delete books. I see the books in the Finder, but when I sync I don't get the books into Kindle.
Could someone tell me how this works?
Thanks very much.
