title: Does IE9 Developer preview (Build 4, v1.9.7.9.16.6000) support the File API?
body: <p>Does the latest IE9 Developer preview (Build 4, v1.9.7.9.16.6000) support the file API? The file API I am referring to is: <a href="http://www.w3.org/TR/file-upload/" rel="nofollow noreferrer">http://www.w3.org/TR/file-upload/</a></p>
  
  <p><a href="http://caniuse.com/" rel="nofollow noreferrer">Caniuse.com</a> says the support is <a href="http://caniuse.com/#feat=fileapi" rel="nofollow noreferrer">uknown</a> and <a href="http://en.wikipedia.org/wiki/Comparison_of_layout_engines_%28HTML5%29#Related_specifications" rel="nofollow noreferrer">Wikipedia</a> says it is not supported but doesn't specify what version of Trident it is referring to.</p>
  
  <p>Unfortunately I don't have a windows machine with Vista or 7 on to test at the moment..</p>
