Hi Tracy,

There's a 'glob' function that helps us grab at all the filenames in a
directory; it lives in the 'glob' module:


There's also a function called os.path.getmtime() function that tells us
when a particular file's been last modified:


If you'd like examples on how to use these functions, please feel free to
ask on Tutor, and we'll cook something up.  Good luck!
