What's the best text editor for use with large files?
Solution 1:
I'm using HexFiend to work with a 60 GB text file and it works great (apparently it can handle files as large as 118 GB).
Solution 2:
I found MacVim pretty good at opening large files.
There's even a plugin to speed it up, if the file is really large.
(If you don't want to compile it yourself, you can download a DMG to install it pre-built.)
