Si esteu treballant com a un usuari normal i intenteu accedir a fitxers que no estan a la vostra carpeta personal és molt probable que se us impedeixi de fer- ho i se us mostrarà un missatge d' error com S' ha denegat l' accés.
If you are running as a normal user and try to access files outside of your own home folder you will often be prevented from doing so and get an error message such as Access Denied.
