Almost every encryption program I have seen for the PC comes with a
zapper program to this, to obliterate the plain-text file.  You
should be able to locate a package for < $50.  You could write your
own fairly simply ... just open the file random, check its size, then
overwrite garbage;  when you delete the file normally, only garbage
is returned to the free space pool.

My personal opinion is that if you are truly concerned about security
under MSDOS you should get another operating system.  If you are
stuborn (sp?), like me, you have to start with good physical
security, add an access control package that never lets you leave the
door very open, and pray a lot.  I have been playing with Watchdog
by Fischer-Innis, and it looks pretty unbreakable -- has anybody
else had any experience.
