                    HttpFileCollectionBase filesData = Request.Files;//Here you can get multiple files.
                    for (int i = 0; i < filesData.Count; i++)
                    {
                        //This code for save your file in directory
                        HttpPostedFileBase file = Request.Files[i];
                        //Save file content goes here
                        if (file != null && file.ContentLength > 0)
                        {
                            string path = Server.MapPath(@"~/DropjoneImages/");
                            bool isExists = System.IO.Directory.Exists(path);
                            if (!isExists)
                                System.IO.Directory.CreateDirectory(path);
                            file.SaveAs(path + file.FileName);
                        }
                    }
                    return Json(new { success = true, message = "" }, JsonRequestBehavior.AllowGet);
