I can't believe it, have been an zsh user for a long time and didn't know this trick until now

Sublime and VS code might try to parse it for syntax highlighting, notepad simply read the text.

vim does this too. If it hangs on you when opening a very large file, don't hesitate to press Ctrl+C. It does not terminate the whole process, but aborts the syntax highlighting, and the editor becomes very snappy.

To proactively turn off syntax highlighting, bracket matching, and so forth, I use

alias vi='vim -u NONE'

which makes it skip vimrc.

VSCode disables syntax highlighting on very large files.
