    /*
     * o ato de renomear  feito em dois passos para que no existam

     * se 'joao' fosse renomeado diretamente para 'maria', existiria um
     * conflito de nomes (existe um arquivo com o nome 'maria').

     * joao -> joao~
     * maria -> maria~
     * joao~ -> maria
     * maria~ -> joao

     * desta forma no existe conflito de nome.
