  title: "Are you sure?",
  text: "You will not be able to recover this imaginary file!",
  type: "warning",
  showCancelButton: true,
  confirmButtonColor: "#DD6B55",
  confirmButtonText: "Yes, delete it!",

    swal("Deleted!", "Your imaginary file has been deleted.", "success");
  } else {
    swal("Cancelled", "Your imaginary file is safe :)", "error");
  }
});
