Okay, but it would also be nice if we could find anything in the manual about it!?

I got a lot of books, which I all gradually editing and then doing irregular backups, depending on the processing progress. Now I wanted my library to bring up to date with this Embed metadata feature (choosed all books at once). Between the two following screenshots 30 minutes passed, then I stopped (Stop). It didn't strain the PC.



New approach, with a selection of 996 books (maybe problematic ones, 5 formats).


Embed metadata → Embed metadata into files of a specific format from selected books (all formats choosed).

After processing there are 5 error messages.

I would like to discuss with you (this refers to everyone, not just eschwartz) the errors - that is probably a tough affair because there are other messages if open these books in Edit book or View mode (not all possible to view).

Is there any interest?
