Como: Copiar pastas
Este exemplo demonstra como utilizar classes de E/S para copiar uma pasta de um local para outro.Nesse exemplo, o usuário pode especificar se deseja copiar também as subpastas.Se os subdiretórios forem copiados, o método, nesse exemplo, os copia recursivamente, chamando a si próprio em cada subdiretório subsequente, até que não haja mais o que copiar.
