from uwasa.fi archives.)

 Q: How can I hide files and directories?

 A: Each MSDos file has a set of attributes: read-only, archive,
system, and hidden. You can hide both files and directories by
turning on their hidden attribute. The usual MsDos attrib command
can only change the read-only and archive attributes, so you'll need
a program that can change all the attributes. One such facility is
attr.com that is contained in the /pc/pd2/cpcug.zip collection
available by anonymous ftp or mail server from uwasa.fi archives.
   Some users have suggested naming a directory as ascii 255, but
this is non-solution, since the directory will show as blank by the
usual dir command.
   A file, or a directory that has the hidden attribute set, does
not show in a directory listing by MsDos dir command. Notice,
however, that there are many facilities which will show also the
hidden files. This means that these methods are good for elementary
hiding only.
  For more advanced protection you need different tools. One
possibility is crypting files. There are many crypting facilities
around including my crypter.exe in the /pc/ts/tsfcom23.arc file
utilities collection available from uwasa.fi archives.
