File size increase if open and close without saving

John F · Today, 02:37 PM

I'm using the calibre editor from within calibre and noticed that if I open an epub and close the editor without making any changes, the file size grows. I noticed that the file size went from 1.1 - > 2.8MB.

Is this expected behavior?

I normally remove fonts, lossy compress by 50%, and remove unused classes.

calibre version 6.22.

Thank you.

Check whether you have "Update metadata embedded in book when opening" checked in the editor under Edit, Preferences, Integration with calibre.
