title: Why can't I see contents of /storage
body: <p>If we use the Android APIs to get the external storage directory, we get something like, <code>/storage/emulated/0</code>. If I run a recursive traversal on the same, I get a list of all the files and folders inside listed.</p>
  
  <p>So, I thought of running the traversal on <code>/storage</code> thinking it would return all the public directories present. But, on running the same, I get a null list of Files inside it. For listing the files/folders, i have used the API: <code>File.listFiles()</code></p>
  
  <p>Why is this happening and how can I get a list of all publicly accessible files/folders on all the storages on Android?</p>
