file checking between volumes.
my dad has an external HDD with some stuff on it he backed up earlier. he wants to check what is on the external, as it may contain some stuff he wants, but may since have deleted without meaning to from his mian HDD.
is there any way of comparing the two volumes?
he wants to just compare my docs on his main HDD and my docs on the external rather than the WHOLE volumes, as it would just pull up a huge list of all the system files that arent on the external. im sure ive read about this before...
thanks in advance.
