newbie question - 218 epubs not imported properly - why?

evapaula · Today, 03:27 AM

Hi there,
I started two days ago to manage all my epubs I collected over the years and because I have a device since one month (a tolino). I have 609 files in a folder and tried to import them to a new calibre library. But 218 books were not properly imported. I find them now in a folder "Unbekannt" (unknown) and if I click on the book to open it in calibre, it says the book has no format (if I translate it right from german, sorry). But these are "normal" epubs, I can open them on my device or in MacOS Books. What can I do now?
Sorry, I am a little bit lost here. Thank you!

They arent normal epubs they are folders whose name ends with the .epub extension that is how apple chose to store epubs on disk for some weird reason.

These 218 not-properly imported ebooks are all epubs that I can import, read and open in MacOS Books, on the Tolino as well and in other ebook-readers. I have never bought a single ebook via Apple, I have other sources. And I know that Apple stores them differently. From my perspective there is nothing wrong with these epub-files. What might other reasons they are the not imported to calibre? And what can I do now? Start from scratch?
