This is oddly wasteful. The azw3 really doesn’t need to have any image at all since the ones from the azw6 are actually used. The combination I would expect of azw3 without images along with an azw6 is sometimes seen on Kindle devices.

Thanks!

I guess they figure a computer has a TB disk and file size doesn't matter. In the case of K4PC D/L, which file has the "enhanced typesetting" if the azw6 only has images?
