Thanks for all the speculations.

Assuming programmers make it possible for the rest of us to disinfect and convert KFX (and many, many thanks to these wonderful people), I'm curious what one gets when one "unpacks" a KFX.

@jhowell kindly listed the files that make up a KFX with a quick description of what they contain. How close is this to EPUB? E.g., if someone familiar with EPUB were to gain access to the main container, would they find something recognizable and editable? What's in the resource container and metadata container?

  • B00UZSTXL4_EBOK/B00UZSTXL4_EBOK.azw (encrypted main container)

I'm also concerned by @kovidgoyal's assessment a few months ago and wondering if there's anything new to suggest the future is not so bleak:
