Why do people like big .rar and .zip files?

This is the third time I've been cut off in an hours long download from rapidshare and there seems to be absolutely no way to pick up where you left off. I liked it better when you could get an album a song at a time or even as one long mp3 and then chop it up because then at least you kept part of it and could pick up the same download where you left off. I just don't get the appeal of these packets of bundled files that are as big as unbundled with such a big disadvantage. It's too frustrating. I'm going to quit looking or considering an audio blog of my own. .rar and .zip are garbage for this but everyone is going to the formats. Give me the big long mp3 back I say.
