If I have a folder that contains an epup, an opf file, and jpg what is the correct method to instruct Calibre to import the metadata / cover image as well when adding the book? |
Calibre writes metadata to its own database (the metadata.db file). It then creates the .opf file with a copy of the metadata stored in the calibre database and stores it with the ebook files. The .opf file is intended to be used for recovery purposes if for any reason the main database (metadata.db) gets corrupted.
What metadata can be stored inside an ebook files varies according to the capabilities of the format in use. epub books for instance have an equivalent to the .opf file embedded in them.
