  <p>but Internet Explorer does not support this method, but I really need upload the video in all browsers.</p>
  
  <p>I checked the express documentation. Since express is based on <code>node-formidable</code> (which has a progress event), I think there is way to build a upload system with progress bar, right? I just don't know how!</p>
  
  <p>Is node-formidable IE enabled right?</p>
  
  <p>Any way is it possible to build a file upload system in pure espress.js with progress bar?</p>
