Vim 8.0 released

The only one I've used that seems to work well on large (100GB pr more) is EmEditor. Haven't had to touch it for a couple years - it was windows only, and I haven't had to deal with a windows server in a while.

I've always found emacs to work well on relatively large files -- even large files that are partially binary. I use it on 1GB files fairly routinely. Even if do an operation which you realize is going to take too long, it allows you to abort operations with control-g.

"less", on the other hand, I would not really recommend. It likes to do things like synchronously hang to count the number of lines, which is annoying -- although you can control-c to stop it. Emacs does a pretty good job of avoiding hanging to compute a line number in the first place, while still giving line numbers when it can do so without undue slowdown.

less also doesn't work so hot on partially binary files: its wrapping/repainting algorithm gets reaaaaaaaly slow if there aren't linebreaks often enough in the file. And its search function also doesn't always seem to always find things it ought to in binary files. Emacs has neither of these issues.
