The
Tracker is the file manager and navigation tool in Zeta that gives
you a graphical display of your system and personal files. Once
you have opened a folder (directory), you can navigate through the
folder and the rest of the file system. By clicking the up icon
you will move up one directory (to the folder that contains your
current folder, if one exists). The Back button will bring you back
to where you were last.
There are some alternative file manager applications available
for Zeta: BeCommander,
BeTree and Genesis
Commander.
To open a file, simply double-click it. When you double-click a
folder or disk icon, by default another Tracker window will open
on the screen and the contents of the folder or disk will be displayed
in a window.
By holding down the Option (or Windows) key when opening a folder,
the old Tracker window is replaced by the new one.

If you are used to single-window navigation, this can be set in
the Tracker Preferences.

Most of the operations you can perform on a file or folder are
represented in the File menu.

Select an item in the Tracker window and then open the File menu
and you'll see...

Find.... This opens a Find panel that lets you search
for files anywhere on the system, as explained in "Finding
Files and Folders" later in this chapter.
New Folder creates a new folder in this window.
Open and Open With... open the selected item.
Open opens it in the item's "preferred application"--the
application that can best display the data in the item. Open
With... pops open a panel that lets you select some other application,
as explained in "The Tracker - Open
With".
Get Info provides information about
the item in a separate panel.
Edit Name selects the text of the item's name so you can
change it. (The text is also selected for editing when you click
on a name in the Tracker window.) A name can be up to 255 characters
long--anything but a forward slash ("/"). If you change
your mind about renaming a file or folder while editing its name,
press the Escape key to restore the original name.
Duplicate makes a copy of the file in the same folder.
The new file has the same name as the original, with "copy"
(or "copy 2", "copy 3", etc.) added to the end.
Move to Trash moves the item to the Trash
can. The item isn't actually deleted until you empty the Trash.
Move to, Copy to, and Create Link pop
open cascading menus that can show the entire file hierarchy. By
descending the hierarchy and choosing a folder, you can move the
item, copy it, or create a link to it in the chosen folder. At the
top of the popped open menu you'll see a Desktop
icon, as well as the partition that the item lives on. If you choose
Desktop, the item will show up on the desktop. If you try to move
a file or folder to a folder that's on another partition, the item
will be copied (i.e. the original isn't removed).
Identify tells Tracker to try to figure out what sort
of file this is. Normally, you'll never have to use Identify
- Tracker identifies new files as they're created or added to your
system. However, it's possible to "unpack" a bundle of
files in a manner that escapes Tracker's identification mechanism.
If you think a file is unidentified (or misidentified), run Identify
on it.
Add-Ons pops open a list of "modules" that can
process the items you have selected. Zeta provides a couple of handy
add-ons, as described in "Add-ons." You can pop open a
File menu for a particular item in a Tracker window by opening the
item's context menu.
Adjusting the Size of a Tracker Window
Adjusting the size of a window can be done by dragging the right
corner on the bottom of the window. You can then make it smaller
or bigger. Another way to adjust the size of a window, is by simply
to choose Resize to Fit (hotkey: Alt + Y)
Seeing the Tracker Windows that you have open

From the Deskbar you can easily access the various Tracker windows
that you have open, even if they are hidden (faded down on the screenshot)
or on a different workspace then the current one. Choosing a hidden
window will bring it back to it's previous position. You can hide
a window to make more space on a crowded desktop by double-clicking
it's application bar.
