Thanks.

@ZioNemo - Import List only deals with metadata, hence my "especially for the empty books"

You could add the 'format' files to the empty book records with the calibredb add_format command, but you need to specify the book number.

Or you could use the 'one book per directory' Add method with an opf file in each - Third attempt in your original post.
