In
the unlikely evenlthat you
use DOS
2.5
to
slore a
file that
oc-
cupies
1000
or
more
sectors on a
diskette,
the
Disk
Directory for
that
diskette
will show
the
file
as
occupying only 999 sectors.
Similarly,
if
there are
more
than 999
free
sectors on a diskette
,
the directory will show 999
+
FREE
SECTORS. This is nol an
error;
to
maintain
compatibility with programs written for
DOS
2.0S,
DOS 2.5 uses only three-digit numbers to indicate file
sizes
.
Also
,
when you store
files,
DOS 2.5 uses the lowest-numbered
sectors on a diskette
first.
Since the earlier DOS 2.0S under-
stands a maximum of only 719
sectors,
any file created using
DOS 2.5that uses sectors
numbered
720 or above cannot be
properly accessed by DOS 2.0S
.
When you use option A
,
DOS
2.5 displays the names of such
"
extended
"
files enclosed
by
angle
brackets.

In

the files FILE3.DAT and FILE4

which
use
sectors of

mine whether
it

not.
Also

that files occupy-

720

normally,

necessarily,
be the
