Preparing Book for First Read, Please Wait

Solo1959 · 11-09-2023, 10:54 AM

I don't know if I changed a setting someplace. I probably did because I'm always fussing with my computer. But ...

My computer runs Kubuntu 23.10. I am using Calibre 6.29

When I open a book in Calibre I get the notice "Preparing Book for First Read, Please Wait"

I get that notice every time I open the same book. Even if I just opened it and closed it, should I open it again, I get the same notice. I notice this with azw3 and epub. The epub will usually open much more quickly than the azw3 book.

99% of the time it's not a big deal, just a moment's wait. But if I open a larger book such as a study Bible, it can take a very long time to open.

Is there a way I can tell Calibre to remember that it already opened the book in the past? Did I mess up a setting someplace?

Thank you for your help.

calibre prepares a book for reading only the first time you open it. If that is not happening for you, its likely because something on your computer is deleting calibre cache files from under it. By default the cache is located in ~/.cache/calibre you can move it via env vars as described in https://manual.calibre-ebook.com/cus...ment-variables

Thank you for your help. I'll have to figure out how to move the directory. A work in progress. Thank you for the pointer.
