books remain on the sd card custom folder where I save my cc library on uninstalling the app. once I reinstall cc and point to that folder save library, the books dont show up in cc. When I connect to calibre on pc wirelessly, it resends all those books to that folder again. I have a lot of books and it might take hours to transfer. Isn't there a way to just get book meta data from calibre as books are already on phone?
