Run both phases of
Library Maintenance->Library Check - the second will tell you about discrepancies between the database and the folders - and some options to fix.
re missing opf files - the only way I know of to create new ones is to do a conversion - but there maybe something better so don't rush off down that rabbit hole before others get a chance to respond. Its something that maybe Check Library function could detect and correct
Oh, and there are a bunch of 'goodies' in the
Quality Check plugin that do much of the above and lots of other stuff
