From view pass #name value into the controller method UploadFiles along with the files in form of parameters.

Controller:

public ActionResult UploadFiles(HttpPostedFileBase files, string newName) {

        string newFileName = "";

        if (files != null)
        {
            string path = HttpContext.Server.MapPath(@"~/Data/images");

            bool exists = Directory.Exists(path);

            if (!exists)
                Directory.CreateDirectory(path);

            string extension = Path.GetExtension(files.FileName);
            newFileName = newName.Trim() + extension; //pass newName here
            string filePath = Path.Combine(path, newFileName);
            files.SaveAs(filePath);

        }
        return View();
    }

You can also add current Datetime in file name:

newFileName= DateTime.Now.ToString("yyyyMMdd") + "-" + newName.Trim() + extension;
