Is there anyone who can explain why same books can have different file sizes (as you see sometimes more than doubled!)

And is there a way to compare epub formatted books with each other? So I can check for missing parts (if any)?

Thanks in advance!
Same Pictures, but maybe different resolution? some viewers scale any input to fit the screen.

Do a Tweak epub on each version, paying attention to the file sizes of the various component pieces (Cancel when done, you don't need to save)
