I want to put all of my kindle purchases in my calibre library but even though I have them all downloaded to my pc app, they are not all in the kindle content folder for me to copy over.
Some of them are there but several are not.
I can read them in the app but they aren't in the content folder.
I have tried removing all the books from the pc app and re-downloading them and the same ones are still not appearing in the content folder.
Any idea why this is and what I can do about it?
