I used Kindle Unpack in Calibre to unpack a .mobi file, so I could correct mistakes in images and text. It was easy - images were JPGs or JPEGs and text was .html or .htmlx files. Now I need to repack it all as a .mobi file and I'm stumped. The folders I have before me are now:
- HDimages (empty folder)
(it looks like the the last 4 all go back into a kindlegenbuild.zip file.
I've looked for a plugin for Calibre that does it, but no luck.
