Unable to restore databasecalibre - Page 2

Remove them and add them back using the Add Books button. Don't add them directly to the library folder.

the metadata.opf in each folder has the same info that was in the DB at the time the OPF was created. It is a snapshot that Restore uses. If it was wrong before, it is probably still wrong.
Adding books to a fresh Library is probably more likely to be correct.

The problem is:

-I have no idea how many books are missing...unles there is a way to get the list of books registered in the database for comparison

- adding books means there are two folders of the same book...removable via utilities easily, but I understand it is not good

I do not understand the retoration of the database...when there are no database,Calibre mooks for books and associated metadat...so why take some and ignore others?

Yes, there is. Create a new empty library and copy all the books in the old library to it via the GUI (NOT via the File Explorer or directly from the folder!): select all -> right-click -> copy to library (delete after copy). The book list in the old library should now be empty. Everything that remains in the library folder was not in the database and must be re-added via the Add Books button.

Because obviously there is something wrong with those books and metadata.

I have compared the opf of two books, one shown, the other not, the only apparent difference is the Calibre identifier (same as the number in folder title) and the uuid.

This is bizarre . But your suggestion is excellent, ongoing now...
