MATLAB: How to use current path and all sub folders instead of just current path

MATLAB

I want to use all of the subfolders in a path with all of the m files in these subfolders. Is there a way to do that. I downloaded this program: http://www.cerr.info/about.php and it can't find files in sub-folders. This program was used on MATLAB 6, but I am running 7. Do you think that might be the issue?
Thanks,
Chris

From the command window, got to File>Set Path.
Then select Add with subfolders.
