You need to check out editors that do not simply load the file, but memory maps them. For example the latest version of Notepad (yes!) does just that:

But also UltraEdit should also be able to do that:

Linux tools such as less have memory mapped file support as well. But that is probably not an option. Maybe cygwin...?

A compilation of options can be found here:

Last time I checked notepad it was hanging on large files or outright out of memory loading them(nit to mention slow).

It requires registration for the community version, but seems to run well so far.

For my emulator dissasemblies which are as large as yours (and really for anything) I use Sublime. It is great as it works and looks the same across all OSes I use: Windows, Mac and Linux: https://www.sublimetext.com/

Just tried that Sublime editor. It still hogs memory(I see it going up to 5GB RAM just starting to load my 16GB log file):S The only problem I've still got with the Liquid Studio editor is that it doesn't seem to display or be able to use line numbers in large text file editor mode?
