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.
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.
