Why the size difference between kepub & epub.
I today loaded the jack higgins book Flight of Eagles into the latest version of calibre, so that I could add it to a series. This was originally a kepub which on my Glo shows as being 1.5mb big. When I had added the series info I noticed upon sideloading the book back onto my Glo, and went to delete the kepub version that the epub was only 634kb in size.
Does anyone know why the same book should be vastly different in size betweek the kepub and the epub?
Incidentally when I altered the series info using edit metadata and typing the series name into the series box it did not work when I saved, so if anyone could explain how to get calibre to save that information in a format that my kobo's (2 wireless, 1 mini & 1 glo) could use I would be grateful.
