I'd like to use "File Inspector" to quickly check config files like .zshrc, .viminfo, and also server config files elsewhere. But these types of files never extensions which seems to mess-up File Inspector ability to open it and give me a quick view of the contents.

/usr/bin/vim as the default app is exactly what I'd want, but only apps in the Applications folder are offered as choices.

Am I supposed to install a vim app (in addition to /usr/bin/vim) from the App Store? And is it even possible to configure "File Inspector" to open files with no extension by default with vim?
