You’ve probably discovered the new Zip-o-Matic Tracker add-on already. But did you know you can launch Zip-o-Matic as a free-standing application, rather than as a Tracker add-on? (you’ll find it in /boot/beos/system/add-ons/Tracker/). Do so and it will sit there patiently, waiting for you to drag any collection of files and folders into its interface.
