Be careful when you unzip files. Many will put things in the right directory for you, but some won't. Preview the .zip before you extract it. I'm sure there are instructions on the website for the Wardrobe Wizard Demo that tell you how to run a Python script. The basics are this: When you click on 'File', the pull-down menu has an option for 'Run Python Script.' Click that, and then you have to tell it where to find the script you want to run. On that same 'File' menu, there is an export option. If you need to export something, choose 'Export.' Then you choose an export format. After you choose the format, the hierarchy editor will appear and you can choose the specific props you want to export.
