On a UN*X type system, the mode number denotes the permission in octal,
where 1 = execute, 2 = write, 4 = read. And the three numbers are for
user, group and other. So a permission of 644 means read & write (4 + 2)
for the user, and write (2) for both the group and everybody else. Of course
this means absolutely nothing in a single user MS-DOS system, where there are
no "group" and "other".
