I'm trying to cleanup my humungous library of almost 10,000 books. Duplicates were created when I moved Calibre from a Windows to iMac machine several years ago. It was more than I could deal with at the time but am now trying to fix my library. I have thousands of duplicates using binary and title/author matches. I removed duplicate formats using binary but still have the now empty books entry.

Is there a way to remove thousands of entries based on various criteria? Specifically, I'd like to be able to remove entries based on Empty or Original_epub formats, older date vs. newer date, etc. It's just way too many matches to do each duplicate group at a time!

I have the updated plugin running on Calibre 6.29 (most recent version for my aging Mac).

Thanks!
