Como pueden ver la variable "carp1"; "Emp1" son constantes pero la carpeta siguiente corresponde a los días del mes.

La idea es como hago para que cuando ejecuto el script le pase por parámetro el nombre de la Empresa y haga un recorrido por las carpetas que y vaya haciendo la copia hasta que consiga la ultima carpeta.

Desde ya mil gracias....
