On the Amiga, the term "Preferences" refers to the set of programs and data used to configure the machine's working environment. They come in two basic varieties: system preferences (the basic ones in the operating system) and application preferences (any you choose to add).

Workbench's Prefs directory
Fig. 12.1: Workbench's Prefs directory.

A variety of editors in the Prefs drawer of Workbench allows the user to set various system defaults. These represent the system preferences. Some of these control settings for peripherals such as printers, while others control the look and feel of the system. The Palette editor, for instance, allows the user to set the default colours used by Workbench.
