 `nnn` is probably the [fastest and most resource-sensitive](#performance) (with all its capabilities) file browser you have ever used. It's extremely flexible too - integrates with your DE and favourite GUI utilities, works with the desktop opener, supports bookmarks, has smart navigation shortcuts, [navigate-as-you-type](#navigate-as-you-type-mode) mode, disk usage analyzer mode, comprehensive file details and much more. `nnn` was initially forked from [noice](http://git.2f30.org/noice/) but is significantly [different](https://github.com/jarun/nnn/wiki/nnn-vs.-noice) today.
