Typically the KF8 section is delivered to reading devices an AZW3 file with low resolution images. The CONT section may also be delivered in a separate AZW6 file. Kindleunpack does not handle that situation and neither does calibre as far as I know.

I vaguely remember that there was a special situation where the combined KF8/CONT could be delivered by Amazon as a single file, but I'm not sure about that. If such files exist then the -i option of Kindleunpack will work with them also.
Is there some utility that will show whether a KF8 file has a cont section without unpacking it?
