title: uploadify file object structure
body: <p>Can anyone tell me the structure of the uploadify file object (used by methods such as onSelect and onUploadSuccess). I have scoured the official documentation but with little success; although I know I can access <code>file.name</code> from the documentation (and after a bit of trial and error I know I can also get <code>file.size</code>), I have no idea what other properties I can get my hands on.</p>
  
  <p>Can anyone shed any light on this? Many thanks.</p>
