filesize

I have an file input tag in my web app. I'd like to check that the file isn't too big before sending it to the server. Of course, I still have validation server side. Is there any way to do this with JavaScript? It must work in IE7+ and FF3+. Thank you.

EDIT: somefileinputobject.files[0].filesize works in FF, but not IE.
