title: Is it possible to download data via Javascript and then reference that data via a file path?
body: <p>I would like to do this:</p>
  
  <ol>
  <li>Download data from a server via Javascript (this I know I can do)</li>
  <li>Store it on the disk (I know I can do this with IndexedDB)</li>
  <li>Reference that data as a file path. (Example: If I download an mp3, I'd like it to be able to pass it into an HTML5 audio tag as "foo.mp3")</li>
  </ol>
  
  <p>Is #3 possible? </p>
  
  <p>I know I can just use base64 and make a data URI, but that is slow and (at least for audio) doesn't appear to work on Android nor iOS (I've tested this with plain HTML5 audio tags and SoundManager2).</p>
  
  <p>Note: I am only interested in cross browser, cross platform solutions.</p>
