Plain ol ASP

// create a new Session variable to store the users name
Session ( 'File' ) = 'myFileName';

// display the name in any page on your site
Out ( 'Your name is ' + Session ( 'File' ) );
TedInAK is absolutely correct.  You can't set or get the file input values even though it appears to be a normal input tag.  Both previous answers are possible solutions, though I would recommend using AJAX to get new content and modify your page without having to reload.  

With ajax, you can submit information to your server, and retrieve the results without reloading or redirecting the page.  It's quick, nifty, clean, and it's becoming quite popular so there are many resources to help you out.

One i know if is which is a jsp library for using ajax.  It comes with several examples with source code.
