The KFX Input plugin locates all of the files that make up the book and packs them into a kfx-zip file. If DRM removal is unsuccessful that is what you get as the result of the import in your calibre library.

Still to soon to tell exactly what is happening, but my best guess is that Amazon's new KFX DRM is able to be changed on the fly somehow. That would indicate they have a stronger type of DRM than they have used previously.
