Below are the topics and course materials we are learning today.

File Search Utility

A completed version of the project we began in our previous session is location on this page. This program contains all the functionality of the classes we began writing along with some extra features. In this lesson we are going to break down the File Search utility and try to understand how its various parts interact with one another.

Main Screen
