Code:

<html>
<head>
   <title>Check the Size of a File -- Javascript</title>

    <script language="JavaScript">
    function CheckFileSize()
    {
        var objSize = new ActiveXObject("Scripting.FileSystemObject");
        var strFileName = objSize.getFile(document.frmFileUpload.strFile.value);
        var SizeOfFile = strFileName.size;
        alert(SizeOfFile + " bytes");
    }
    </script>
</head>
<body>
    <form name="frmFileUpload">
        <input type="file" name="strFile">
        <input type="button" name="btnSize" value="Show file size" onClick="CheckFileSize();">
    </form>
</body>
</html>

The above code snippet will work only if ActiveX is supported @ the client end.
