Which is why I wrote NOSHARE.COM, a TSR that causes any attempt to open
or create a file with FCBs to return "failure". This tiny program doesn't
cause problems with file sharing (which one tends to get with SHARE)
and should prevent against disk corruption. It also effectively tells you
about old programs that should be tossed.

Because Microsoft doesn't document what SHARE actually does, use
NOSHARE at your own risk (it does work for me). There might be something
else I should guard against but don't. As an endorsement,
Microsoft recommends *against* the use of NOSHARE, so I figure it has
got to be good :-).
