When adding duplicate books in epub format to Calibre sometimes only file size differs. Per example I see (both stored in different directories of course):
book.epub 0.2 Mb
book.epub 0.5 Mb
Opening the books in Calibre with E-book Viewer shows no differences. All looks exactly the same: same pictures, same text, same page count etcetera.

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!
