Because when I try to add the folder where I have them, it locates them but it takes an average of 10-15 seconds per book and of course, an average of 13 seconds for the 25,000 epubs, we are talking about 325,000 seconds = 5416.6 hours = 90.2 hours = 3.76 days. Almost 4 days to add the library! Do you know any way to add it faster?

Thank you all very much and happy reading!
Are all the files in a single folder? You don't say what OS you're using, but Windows does not like having more than about a thousand files in a directory. I've built systems around breaking that up for performance reasons.

What happens if you try loading from a folder with, say, a hundred files in it?

If that makes a difference and you're storing everything in one folder, perhaps break it up into folders of 500-1000 files instead.
