Unerase File
Under certain
conditions,
Unerase
File
enables you to recover
files that
hav~
been deleted
.
When
you
delete a
file,
it is
not
actu-
ally removed from the
disk
-
DOS just marks
its
di rectory entry
as erased, bars the file from normal access, and marks the
space it occupies as available for new files.
Ullerase File may also enable
you
to recover files that were
opened for output
(for
example, with the
command
O
PEN
#1,
8,
0,
" D:MYFILE.DAT"
)
but not
properly closed for some
reason
(for example,
if
you
pressed
[
Reset
)
before closing the file). Such a
file may occupy a part of the disk to which you cannot normally
regain access. Unerase File can be used to access 1he file.
Note for advanced
users: You can recover a
file
open
for
output
by unerasing it only
if
there are no bad links
in it.
