Use:

$(':file').each(function(){
  // your code to handle input type files.
});

Or:

$('input[type="file"]').each(function(){
  // your code to handle input type files.
});

More Info:

http://api.jquery.com/file-selector/

When do you want to get the input field? after clicking a button? or changing the input field? if you add dynamic the input field than you can maybe better use the live option.

$('input[type="file"]').live("blur",function(){
        $('input[type="file"]').each(function(){
              // you can put your code here
            });
    });

see: http://api.jquery.com/live/

above code is from jQuery 1.4

Better give more information next time
