and you are probably generting joint MOBI files for which updating of metadata is not possible so plugboards wont work.

Hi,

I read the linked discussion, I tried, as suggested in the discussion, to load one book at a time, then save the cover by replacing it in the hidden folder of the Kindle "system / thumbnails", a bit complicated as a thing because it would force me to load a only book at a time and each time disconnect the Kindle from the PC and reconnect it, but I have seen that the thumbnail created is actually that of the loaded book, but the one displayed on the device is the default one of the Kindle.

Can I generate "not joint" mobi files?

Thanks!
