hola juan
este es un código que uso yo.
Primero declaro las funciones de la API que necesito
y después hay una función a la que le pasa el archivo de origen y destino (ruta completa), la direccion IP, el login y password y un flag por si quieres colgar o descargar el archivo, y devuelve true o false si ha sido correcto
Espero que te valga. un saludo, Adolfo
