Folder sizes and disk space usage in windows 7 (Vista).

Sometimes you want to know what is eating up space on your drives. In the past I've utilized "Folder Size" to accomplish this task. It would list folder sizes as a separate column within Explorer. It was easy to control the service on the fly through a batch file. Well Windows Vista / 7 came along and ruined my fun. Microsoft has changed how developers can interface with explorer, so I can no longer utilize Folder Size. That's not cool. So here are a few free alternatives we can use to accomplish folder sizing / disk space usage. Maybe SP1 will fix this issue.
