Disk Triage - Windows Integration
When Disk Triage is installed, it integrates into the Windows Explorer Pop-up menu. This allows you to right click on a directory and choose "Analyze Directory with Disk Triage..." from the pop-up menu. This will start Disk Triage and automatically populate the Directory to be Sized edit box. A nice quick, simple way of sizing and analyzing a directory.
