title: Is there something similar for emacs like vims's NERDtree
body: <p>For vim there is a filesystem explorer called NERDtree: <a href="https://github.com/scrooloose/nerdtree" rel="noreferrer">https://github.com/scrooloose/nerdtree</a></p>
  
  <p>Surely an alternative or superior package exists for Emacs?</p>
