[Zope] polling a file system

Hi gang! i hae a 20 gig drive full of image files (png, jpg, gif), and i would like to catalog the file name and location programatically. i'm wondering if and how it may be possible to run a query on zope that would scan and catalog a file system (even a windows hard drive), and populate a database based on file name, type, size, etc. the data entry part, i'm sure i have down, my big question here is how to scan the hard drive. Thanks in advance, Shaun
