Database

[Bardman]

Why is the databse such a mess. Try to remove al the doubles in my 60 000 booklibrary looks good but when i export the books to a drive and import the again in a new library there is a 5o Gigabite difference.

And when ik look back at the old db there are still a lot of doubles the db that are NOT removed but only not showing up in Calibre

BTW it took me more than a year to clean.

Presumably because your library is a mess. Have you run a library check, especially the part that checks if the database matches the actual files?

I would do a database rebuild. Then run the Find Duplicates plugin to find any duplicates.

I recently ran Find Duplicates and found a number of duplicates. I deleted the earlier copies.

I run Find Duplicates regularly. I also run Check Library regularly, and check whether the database and the files match.

I suspect the OP has manually added and deleted files to/from their library folder and now wonders why their database doesn't reflect the files in the library.

That sounds right to me.
