title: Remove 'All Files' option from HTML file input
body: <p>I am using <code>&lt;input type="file"&gt;</code> to upload <em>audio</em> files.</p>
  
  <p>To do that I am using <code>accept="audio/*"</code>.  Because of this, the browser's file-select dialog shows only audio files by default.  However, there is an option called "All Files" in that dialog box that I don't want.</p>
  
  <p>(note - Any solution in Javascript , jQuery and AngularJs is also welcome)</p>

  <p>How can I disable/remove the "All Files" option?</p>
