to solve the problem in a straightforward way, have a look at 'os.system',
and see if it will do what you want.

I haven't used the windows version of python... perhaps someone will be able
to answer this question and explain the reasons why nicely.

have a look at the pgp docs, and see if you can pass the encrypter/decrypter
a filename that contains the list of files.. this will be much easier to
handle, and will probably perform better. there are definate disadvantages
to calling 'os.system' *many* times in a loop, especially when you are
invoking the same program over and over again. more important, though,
should be to get an initial version of the code working, and see what
happens.
