To the best of my knowlege, there is no way to preload the value of a file input field or to programmatically load it.
I've tried with Mozilla and it throws a javascript security exception. (I haven't tried with MSIE). To do so would be a security threat. Any webpage could have a hidden form that looks for a particular file (or set of files) and submits itself as soon as the page loads. The user would have no way of stopping it or even knowing that it's going ont.
