I pulled a full backup of the kindle app. Then to extract the backup file I found Android Backup Extractor, abe.jar https://github.com/nelenkov/android-...063121-8fdfc5e

After banging my head against that rock for a while I found that abe.jar needed at least Java 11 yet for some reason Oracle has not released a JRE for Windows later than version 8.x while the JDK is at 20.something.

So I uninstalled JRE 8.x and installed JDK 20.x then I had to do some manual editing of environment / path to grab Windows by its nose and rub its digital face in the location of where Java.exe is now - since Oracle couldn't be bothered to have its installer do it properly. (Is oracle trying to completely kill off Java by having such terrible support for the largest software platform?)

FINALLY I could run
java -jar abe.jar unpack backup.ab backup.tar

in the directory where backup.ab was then use WinRAR to unpack backup.tar

And there, buried in a subfolder, were all the books, both the visible ones in Android/data/com.amazon.kindle/files and the others it has squirreled away somewhere else.

Calibre can work with those. I'd previously pulled a Kindle backup from it to get the serial of it for DeDRM.

If someone wants to use any of this to add to how to work around Kindle PC DRMing everything (even books the author requested to not have any DRM) have at it.
