After I sent a lot of books to my device (kindle), I noticed some strange author names for the subfolders on the device and knew that some of the metadata was wrong (usually due to the author_sort not matching a change in the author). After having corrected the metadata on Calibre, what is the best way to sync those updates to the device?
Do I need to delete the ebooks first from the device and then send it again? If I don't delete it and just send it again, will calibre be smart enough to remove the incorrect author folder and content in the process?
I wish I could select all 500 books in calibre and have a 'fix conflicts on device' button.
