title: What is com.android.externalstorage?
body: <p>Despite this being a simple question I cannot find the answer on <a href="https://www.google.com/search?ei=jtAuW9CtIsGZjwSh-YEI&amp;q=what+is+com.android.externalstorage" rel="nofollow noreferrer">google</a> or <a href="https://i.imgur.com/NWZ5ICr.png" rel="nofollow noreferrer">stackoverflow</a>.</p>
  
  <p>When I use the following code I get this result <code>//com.android.externalstorage.documents/tree/primary:Podcasts</code></p>
  
  <pre><code>var intent = new Intent(Intent.ActionOpenDocumentTree);
  intent.PutExtra("android.content.extra.SHOW_ADVANCED", true);
  intent.PutExtra("android.content.extra.FANCY", true);
  intent.PutExtra("android.content.extra.SHOW_FILESIZE", true);
  </code></pre>
  
  <p>Can you help me understand the parts of my result? </p>
