title: Creating empty directories in a Yeoman Generator
body: <p><strong>How does one create an empty directory via a yeoman generator?</strong></p>
  
  <p>I've looked at <a href="https://github.com/sboudrias/mem-fs-editor" rel="noreferrer">mem-fs-editor</a>, but as far as I can tell, directories are only created when a child file is created. I've tried creating a file in a sub directory and then deleting the file, but this doesn't work (I assume because mem-fs is prebuilt completely in memory, when it comes to write to disk, empty directories are not written). </p>
