También puedes usar `File()` con `UploadFile`, por ejemplo, para establecer metadatos adicionales:

## Subidas de Múltiples Archivos

Es posible subir varios archivos al mismo tiempo.

Estarían asociados al mismo "campo de formulario" enviado usando "form data".

Para usar eso, declara una lista de `bytes` o `UploadFile`:

        public ListIterator<E> listIterator(final int index) {
            return parent.listIterator(index);
