and if you really want to
hide, obfuscate and deceive
your files, you could switch
the position of two or more bytes
in the binary data of your files,
for example:

If your file named "DoNotOpen.zxc"
had the character 50 and 51 like these: 
%*
you could write a function that
revert the position of these
character like these: 
*%
and later for opening the file
you restore them to their
original position: 
%*

Notice that you could do the same
with many bytes (characters),
not only using 2 characters.

You had to test how many char swaps
works better to lock your files.

i had wrapped binary files 
(like sounds, images and stacks)
with two encrypted md5digests, 
one for the file uncompressed
and other for the compressed file.

Of course, it's necessary to
use a script in RR to unwrap, 
verify, decompress and open 
these files.
