Not with HTML alone. Maybe with Javascript.

Here this may put you in the right direction:

hmm, most links on that thread are dead and the only potential solution is using activeX

Code:

function A()
{
var oas = new ActiveXObject("Scripting.FileSystemObject");
var d = document.a.b.value;
var e = oas.getFile(d);
var f = e.size;
alert(f + " bytes");
}

</script>
</head>
<body>
<form name="a">
<input type="file" name="b">
<input type="button" name="c" value="SIZE" onClick="A();">
</form>
</body>
</html>

back to the JS forum I think.
