title: Reading file chunk by chunk
body: <p>I want to read a file piece by piece. The file is split up into several pieces which are stored on different types of media. What I currently do is call each seperate piece of the file and then merge it back to the original file.</p>
  
  <p>The issue is that I need to wait until all the chunks arrive before I can play/open the file.
  Is it possible to read the chunks as they are arriving as opposed to waiting for them to all arrive.</p>
  
  <p>I am working on media file (movie file).</p>
