Apple includes a small program with every new Mac called Automator. It is a scripting program that scares away most people, but with a little instruction can be very helpful.

One of the items I wanted to automate was to save my purchased iTunes downloads to my backup hard drive. I found a workflow for that and it streamlined the whole process.
