Note:
System
diskettes
contain
some
files
which
are not
shown
in
any of
the
directory listings.
You
may
delete these
files
with
a special
form
of
purge:

:d {file
type)
The
asterisk tells
trsdos
to
ask you
if
you want
to
delete the
System
files.
If
you do delete
them,
the diskette
becomes
a data diskette
and
may
only be used
in
Drive
1,
2 or
3.
The
other parts
of
this
command
are as
explained
previously.
However,
be
sure
to
do
the
purge using Drive
1,
2 or
3,
since the diskette will
become "non-
system" during
the
purge.
