Enhanced typesetting is a feature of KFX format and doesn't use azw3 or azw6 containers at all, although it splits up the content of the book in a somewhat similar fashion. There is a main KFX container with most of the book content and structure, a metadata container with the metadata and cover image, additional containers for font and image resources, and a DRM voucher with encryption keys.

There is another confusing aspect of this. Recent versions of Kindle for PC give book file names different extensions than were used previously. The extensions .azw3 or .azw6 no longer actually appear for those types of containers. The main file for each book has an .azw extension regardless of its type. And auxiliary resources, such as azw6 containers, now use the extension .azw.res. You now have to examine the file's contents to determine its actual type.

Kindle for PC is not like iTunes. It is a stand-alone app and cannot transfer books to/from other apps or devices. For those books that have DRM (the majority of BPH published books), Amazon's DRM locks them so that they cannot be read if transferred elsewhere, even on devices registered to the same Amazon account.
