f you just want to view a large file rather than edit it, there are a couple of freeware programs that read files a chunk at a time rather than trying to load the entire file in to memory. I use these when I need to read through large ( > 5 GB) files.
Large Text File Viewer by swiftgear http://www.swiftgear.com/ltfviewer/features.html
Big File Viewer by Team Walrus.
You'll have to find the link yourself for that last one because the I can only post a maximum of one hyperlink being a newbie.
