    I am using mulitple uploader, and need to get the file size at client side when user selects the file.
    Is there any direct method or property to get size?
    For now I am using the below code, but it is not working in IE

     function selectedFile(sender, eventArgs) {
       var inputs = sender.getFileInputs();
       for (i = 0; i < inputs.length; i++) {
                        if (navigator.appName == "Netscape") {
                            size = inputs[i].files[0].fileSize;
                   else if (navigator.appName == "Microsoft Internet Explorer") {                  
                            var filepath = inputs[i].value;
                            var SizeINIE = User_book.GetFileSize(filepath);     //This always returns 0 as the file will not be existing on server
                            if (SizeINIE != null) {
                                size = SizeINIE.value;
    Can anyone provide me solution for this ASAP?

    Hi Mansi,

    The problem you are experiencing is due to the fact that IE doesn't support this kind of functionality in general.
    As you have noticed this is working in Firefox and Chrome but for now there is now way to achieve this functionality with IE.

    Kind regards,

    Actually there is something I`d call a non-solution - it does require you to create a non-secure activeX object:
    var filesystem=new ActiveXObject('Scripting.FileSystemObject'),
    fullpath=value_of_the_file_input_dom_element;// you know how to get this
    var size_bytes=filesystem.getFile(fullpath).size;
    M$$ tries to create everything in it`s "own" way. For this to work, you need to select "Initialize and script active x controls not marked safe for scripting" in Security->CustomLevel
