the

has
a

files.
The
size
of
the
reserved
space
for
this
partition
varies
according
to
the
model,
operating
system
and
software
of
the
computer.
For
the
sake
of
safety,
this
partition
is
not
evident,
which
is
commonly
referred
to
as
a
“hidden
partition”.
In
addition,
after
the
hard
disk
is
partitioned
or
formatted,
the
system
will
assign
a
certain
amount
of
hard
disk
space
for
the
system
files.
For
the
above
reasons,
the
available
hard
disk
space
indicated
by
the
operating
system
is
always
less
than
the
computer’s
nominal
hard
disk
capacity.
