FWIK, Ultra Edit supports edit large files, it won't load the whole file into memory but load some and edit some. But it's not free.

I guess there are many editors which based on mmap() will do the work.

Not mmap() but file mapping. msdn.microsoft.com/en-us/library/aa366556%28VS.85%29.aspx – Ignacio Vazquez-Abrams Dec 3 '10 at 5:46

LTFViewr5u is the best solution: 

This program was designed for viewing large (>1GB) text files.
It uses little memory and is able to open a gigabyte file instantly.
Background file indexing makes browsing even faster.
It allows the user to perform high-speed complex text search by means of plain 
text or regular expression.
No installation is needed.
The executable is only 572KB!
