unfortunately not. Even zipping it reduces it by around 5 megs...
My advice. Search for a download resume program. Then find a fileserver that does allow resuming.
Start the download early at night, then wake up in the morning.
or get a friend who has both broadband and a CD RW and let him burn it for you. I downloaded it at my high school and did that.
I know the pains of dial-up, I've got it too. But with ESF, you've got models, sounds, coding, and all sorts of nice stuff, so a large size is unavoidable.
