I know I can manually set the output to AZW3 via Preferences/Behavior. The list of preferred output formats from the Behavior dropdown list does not show other than mobi (no old or new mobi). I have no idea if this is the old or new mobi format. My question: the Calibre welcome wizard chooses mobi as the preferred output format when the Paperwhite option is chosen. I had trouble emailing some of my lost ebooks and had to side-load them. I bought a new Paperwhite 2014 late last year and have just been reading through what I've bought since plus a number of old titles that somehow came across in an incomplete collections that came from the old K3 somehow.

The DRM seems to be a non event this time around with a simplified plug-in from AA.

Resurrecting this old thread as I am just now getting Calibre up and running on my rebuilt PC (Win 8.1pro X64) and was dreading having to figure out all the DRM stuff I learned (and forgot) 4+ years ago.
