I open multi-GB files often enough in VIM. Just make sure that you've disabled any plugins, as _those_ will often crush under large files. The `-u NONE` option will disable `.vimrc` and thus all plugins as well.

See relevant discussion on Stack Exchange: https://unix.stackexchange.com/questions/139254/why-cant-vim...

Windows have EmEditor.. unfortunately Linux doesn't seem to have any. Hopefully someone can develop a great frontend for the xi editor (https://github.com/google/xi-editor).

Sublime Text is imo near perfect, only thing I miss is the ability to edit multi-GB files (on a reasonably priced laptop).. sadly I believe it will be near impossible for Sublime Text to ever support this.

Emacs with vlf can open very large files by splitting them in chunks. Quiet useful.
