Thanks for the info, that cleared it up.

For heaven's sake, why did Kobo create yet another proprietary format? Don't need to answer, I know the answer, just ranting out of frustration. I love some of their devices, but then you have to jump thru hoops to buy books from them or other sources, liberate them, convert to epub, then re-kepubify to get them sideloaded back onto the device. And then of course you've lost all the ability to do any kind of cloud sync of your notes and reading positions across devices.

Really makes me not want to buy their devices.....they're not one nit better than what Amazon is doing with Kindle, with the sole exception that they support more formats of other kinds. Using 'support' loosely, as in kind of a 2nd class experience on the other formats.
