Erasing Files
You can erase a file
from
a
diskette
with
the
DELETE
FILE(S)
function on the
DOS
Menu.
Erasing out-ot·date
files,
of course
,
opens up space on your data
diskettes
for
storing
more
informa·
tion. After a file is erased from a diskette
,
its filename
disappears
from the directory
for
that diskette.
Caution:
Use
the
DELETE FILE(S)
function with care
-
it
may
be permanent
.
Once you've erased a
file,
only under certain
conditions can you use the OISKFIX.COM utility to gel
it
back.
(See the
DISKFIX.COM
section
,
Appendix
L.)
For

I.
The prompt

allowing you a chance to change your
mind
about
erasing
the
file.
3.

and press
(
RetI.rn
I
to
erase the file
.
With
wild
cards in your
filespec
,
you can erase as many files as
you wish in one operation. To try
this,
erase
the
two remaining
copies of files with the
BAS
extender on your diskette
.
Follow
the
same procedure
you
use to erase one file
,
but
when
your
com-
puter prompts you to enter
the OELETE FILESPEC
,
type
01
:'

(or
02

if you are
using
Drive 2).

delete that file. When
you
want
to
erase
sev-
eral

the
files in a group
that
you
specify with wild
cards
,
simply type

Retln1
]
as the
name
of
each fite
that you want to
preserve
appears
.
This
operation takes
less
time
than going
through
the entire
DELETE
FILE(S)
procedure
for
several individual
files.
