I tested with 3 books in the original library and gave each a star rating (I don't use star ratings). I then saved and a OPF was created for each book. I then closed Calibre and started it again and the corrected opf file was still there.
When I imported the 5143 books into a new library 108 showed the date added as 20 August. I have not added any books since 18 Aug. Each of those had an opf file but either the metadata values were missing or incorrect when I randomly checked the books.
I assume that adding books through "Add from Folders or Sub-folders"creates an OPF file. Interesting that my check on the number of opf files showed a 108 books missing opf files.
To be honest 108 books without metadata is not a problem. It would have taken me less time that try to identify this problem. I have a worry that some of the books which do have opf file in the original library have incomplete opf files.
So how to I rebuild the metadata library? I dont have a metadata backup.
