Stop using MOBI eBooks on your Amazon Kindle!

November 1 Amazon will discontinue the MOBI file format for eBooks. They have switched to more modern file formats - EPUB and KFX. In this video I talk about when to use EPUB and when to use KFX files. And also what works wirelessly and what does not when sideloading eBooks to your Kindle e-Reader. I also show different formats in Calibre Book library software.
