The Advanced preference tools enable you to customize the behavior and appearance of your applications, panels, and other user interface items. You can use the Advanced preference tools to configure file types, your default applications, and your panels. You can also use the Advanced tools to customize your sessions and startup programs. This chapter describes how to use the Advanced tools to customize your desktop environment.

The CD Database
preference tool
enables you to configure a CD database that your system can query. A CD database

Use the File Types and
Programs
preference tool to specify how files of various types
are created, displayed, and edited. For example, you can specify that if a
file is a plain text file, the file is launched in a text editor.
Nautilus

the contents of a file to determine the type of a file. If the first lines
do not determine the type of the file, then the application checks the file
extension.
