I have a large library that I backup daily with a program that shows me which files have changed before the backup starts. As a consequence I have a good sense of when something unusual happens.

This morning I imported a few books and tagged them. I then backed up my library expecting to see the new files for the books I just imported plus the usual library database and configuration files that change each time Calibre is executed.

In addition to these expected changes there were several dozen opf files that changed. The books associated with these opfs seem random. I saw no problems in the metadata of a few of these books that I inspected. I can think of no action I did that could have caused these opf changes.

I am not sure if the latest version of Calibre 0.8.55 is doing some benign background housekeeping. Or if indeed this is a problem I should be worried about.

I have not seen opf's randomly change like this in the past so I am a little worried.

Please advise.
