i.Hex is a small and free graphical Hex Editor for Windows. I got ticked off at all the lame shareware hex editors out there and just buckled down and wrote my own [lame Free Hex Editor ;)].
If people would like more features or you find a bug, let me know and I'll see what I can do.
Features:
Doesn't load all the file at once. Just a pane of 64K is loaded at any given time, thus it can edit/view very large files almost instantly.
Recent file menu.
Doesn't use the registry.
Oh yeah, it's free, fast and small.
