Yes, another problem...

I'm looking for a Windows text editor that can handle megahuge text files -- such as a Poser .cr2 file. I'm trying to hand-hack the Vicky 2 figure (yes, I know what I'm doing) but I need a plain text editor that won't go wheels-up when I load a 20MB+ file.

Notepad just hands over to Wordpad, and Wordpad can load and save but won't let me make any actual changes to the file when I cut-and-paste the new bits in.

I went surfing earlier tonight and picked up NoteTab Light, which was advertised as "opening any size of file". Opened Vicky2, made the changes, saved... and the file's shrunk from 20-odd to about 11MB. No wonder it wouldn't load... I seem to be hitting a hard-coded limit here, I just can't get the whole file loaded in one go.

OK, here's my question. For you brave souls warped enough to do what I'm trying, what text editor (Win98, and preferably free- or share-ware) do you use to edit huge .cr2 files?
