Free Text Editors to Open Large Text files

Every week in my company, we go through the process of opening large log files (over 200 MB) and search and edit text. We searched out a few Text Editors that can make our lives easier and open these large files without hanging the system. Here are some Text Editors that are free with an impressive feature list:

Vim/gVim (Graphical VIM)

Vim is an advanced text editor that seeks to provide the power of the de-facto Unix editor 'Vi', with a more complete feature set.

Sometimes read-only tools are best for working with very large text files. For example, GNU less.

BareMetal Software also has some nice GUI tools that use the same approach. The free one works OK.

You forgot Notepad++

Thank you everyone for the suggestions.

John.Net - Notepad++ could not handle files larger than 200MB gracefully and that is why it is not in the list.

Another vote for Editpad Pro!

I tried zillians of editors before trying this one, but this was the only one able to immediately show me a 700MB log file. Other either weren't up to it, took at least ten minutes and/or were immediately unresponsive.
