as you know cf mx 7 does not have a built-in zip
functionality.
you will have to install a zip application (i.e. 7zip, which
is free) on
your server and use cfexecute to run it and unzip your file.
if you are on a shared hosting you are pretty much out of
luck - look if
your server has a pre-installed php or other script to manage
zip
archives...
