title: Local file access with JavaScript
body: <p>Is there local file manipulation that's been done with JavaScript? I'm looking for a solution that can be accomplished with no install footprint like requiring <a href="http://en.wikipedia.org/wiki/Adobe_Integrated_Runtime" rel="noreferrer">Adobe AIR</a>.</p>
  
  <p>Specifically, I'd like to read the contents from a file and write those contents to another file. At this point I'm not worried about gaining permissions and am just assuming I already have full permissions to these files.</p>
