Perhaps this is a dumb question, but why on earth are you manually sifting through 600+ mb text files by hand. Thats WAY too much to do anything useful with, as a human being. If you know what information you want, maybe the better route would be to write some short thing that pulls out of it the part you need.
I routinely deal with huge text files. Typically on the order of 100mb to 1gb, and tens of thousands of them at a time. There is nothing even remotely productive that I can manually do with that information. I can, however, write a paragraph-long script that parses 100 gbs in one whack, and generates a graph of the feature I'm actually interested in. That's information that I can, as a human being, actually do something with.
