OpenTracker
OpenTracker.sf.net offers free, open-source versions of Tracker and Deskbar, the two applications that power the BeOS desktop.

Add-Ons

The Tracker, as many other applications in Zeta, makes use of add-ons. In Firefox for instance, add-ons are called extensions. Zeta it self supports add-ons through out the system. The translator system is built up with a various of different file format translators for both text and images. Both the desktop and Tracker provide access to your system's add-on through their context menus, as explained in The Desktop Context Menu.

###
Tracker Add-ons

Tracker add-ons are applications that can perform operations on individual files or on a set of files. Tracker add-ons are loaded by context. A set of add-ons are always loaded, but others will only appear as an option when you can make use of them. The Add-on DirLiser will only appear when you are working with a directory/folder.

The Tracker add-ons are stored that comes with Zeta are stored in the following directory: /boot/beos/system/add-ons/Tracker. We recommend that you store your add-ons in an other directory: /boot/home/cofig/add-ons/Tracker.

Zeta comes with several add-ons, including:

Backgrounds
The Backgrounds add-on comes handy when you want to set a background picture for a folder or for the Desktop.

Crypt-O-Matic
The Crypto-O-Matic application comes with an add-ons, so that you can encrypt and decrypt direct from the Tracker, without having to first start the application.

FileTypes
The FileTypes add-on lets you change the preferred application for a single file, instead of changing the preferred application for a specific file format system wide.

Squeezer

Summon
Summon is an add-on that lets you easily access the Terminal from any location on your system. It also automatically sets your working location and not home.

Thumbnailer
An add-on that you fast will learn to appreciate is the Thumbnailer. This small tool makes a thumbnail out of a chosen picture or pictures. From the screenshot you can see that all pictures in the folder has been converted to thumbnails. As digital cameras have become more and more common, people are now taking lots of pictures and storing them on their computer. Therefore most operating systems today has support for thumbnails view, as it is consider as one of the best ways of keeping track of pictures, so also Zeta.

In the Tracker settings you can set the size of the thumbnails.

Zip-O-Matic
Zip-O-Matic is probebly the most commonly used Tracker Add-On.

This Add-On tool is used to both compress and archive multiple files in to one single file.

To use it, you simply highlights the files and folders that you want to turn in to a compressed zip file, and then right-click the mouse to open the Tracker's context menu. From this menu you first choose Add-Ons and then Zip-O-Matic. The application's window will now appear and you can drag and drop the chosen files on to it and then start the process of zipping them.

The zipped file will appear in the same folder as the files and folders that you compressed.

***

There are a number of third-party add-ons available from BeBits (http://www.bebits.com/browse/29) for doing such things as viewing archives, expanding and compressing files, viewing file attributes, searching file contents, and so on.
