And I remember another post with the same question snappy told you that's probably as close as you're going to get. You cannot control every browser.

I suppose you could write your own code either something using jQuery or some other JavaScript or perhaps your own c++ class.

I doubt anyone's going to give you a complete cut and paste solution , you may have to take a few months and learn how to code that stuff.

@JLRDW - yes i read this but i click upload button and open a dialog box and open a dropdown list which is custom file and also all files when i click dropdown so i try to disable all file option only show a specifie file please suggest me

i did this using javascript

var _validFileExtensions = [".jpg", ".jpeg", ".docx", ".xlsx", ".pdf"];    

function Validate(oForm) 
{
        var arrInputs = oForm.getElementsByTagName("input");
        for (var i = 0; i < arrInputs.length; i++) 
    {    
        var oInput = arrInputs[i];
            if (oInput.type == "file") {
                    var sFileName = oInput.value;
                    if (sFileName.length > 0) {
                        var blnValid = false;
                        for (var j = 0; j < _validFileExtensions.length; j++) 
                {
                                var sCurExtension = _validFileExtensions[j];
                                
                    if (sFileName.substr(sFileName.length - sCurExtension.length,                               sCurExtension.length).toLowerCase() == sCurExtension.toLowerCase()) 
                {
                                blnValid = true;
                                break;
                            }
                    }
            
                    if (!blnValid) 
            {
                            alert("Sorry, " + sFileName + " is invalid, allowed extensions are: " + _validFileExtensions.join(", "));
                            return false;
                    }
                }
        }
    } 
return true;

}
