title: Launch Windows Explorer from Metro style app
body: <p>I would like to download a file to the DownloadsFolder in a Windows Store App. And then I'd like to bring up a Windows Explorer open on the DownloadsFolder (actually on the folder I create in the DownloadsFolder)
  <br>
  But I can't figure out how to do it.</p>
  
  <p>This stackoverflow question <a href="https://stackoverflow.com/questions/9527644/launching-a-desktop-application-with-a-metro-style-app">Launching a Desktop Application with a Metro-style app</a> suggests using Launcher.LaunchUriAsync. But the documentation claims:</p>
  
  <blockquote>
    <p>You cannot use this method to launch a URI in the local zone. For example, apps cannot use the file:/// protocol to access files on the local computer. Instead, you must use the Storage APIs to access files.</p>
  </blockquote>
  
  <p>And indeed, I was trying to use the "file:" protocol to bring up the explorer window. When I did try this mechanism Launcher.LaunchIUriAsync fails.</p>
  
  <p>If the browser can do this, why can't I?
  Is there a way for me to bring up windows explorer, or is that outside the real of possibility? </p>
