--------------generateUUID is used to creatd individual uid for file

function generateUUID() {
        var d = new Date().getTime();
        var uuid = 'xxxxxxxx-xxxx-4xxx-yxxx-xxxxxxxxxxxx'.replace(/[xy]/g, function(c) {
            var r = (d + Math.random()*16)%16 | 0;
            d = Math.floor(d/16);
            return (c=='x' ? r : (r&0x7|0x8)).toString(16);
        });
        return uuid;
