Hi Danny!

The routine works fine and so does this one.

http://www.pygame.org/pcr/zipshow/index.php

The only problem with all these are that that the time taken to read these
files and to either make a list or send to screen is WAY TOO LONG.
The only one that works without much delay is in the file I have attached.
It is a bit of code that I wrote with verbose print statements to follow
the program in action while testing. As this uses base64 only there is no
secure encryption. Please have a look at it and try to improve it.

Am I doing this correctly? Are these messages getting to the community?

read the files in the current directory and get all files except ones in the exempt list or directories..
Get the file extension.
and convert them by using maketrans without file extensions.
When converting from original files with file extensions, remove the file extension(with the .), reverse it and add it to the begining of the filename.
encode the file.
add new file ext "@lm".
eg: file name -> picture.tiff -> ffit.picture ->AFKDiO$1#&mL at lm.
encoded files added to a directory "coded" which is created if not exist.
decoded files added to a directory "decoded" which is created if not exist.

path = your path where the files are
run = True -> encode
run = False -> decode
