3.4.2 Specifying File Associations
Click .
Use the File Types and Programs tool to specify how files of various types are displayed and edited, and to associate an application with a service so that the application performs the task required by the service.
Figure 36 File Types and Programs Dialog
Use the File Types and Programs tool to configure the following:
- File Types
You can specify how files of various types are displayed and edited. For example, you can specify an icon to represent a particular type of file, or you can specify that if a file is a plain text file, the file is launched in a text editor.
The file manager and other applications check 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 filename.
- Services
A Uniform Resource Identifier (URI) is a string that identifies a particular location in a file system or on the Web. For example, the Web address of a Web page is a URI. A service is a protocol or task that a URI requests. For example, the http://www.gnome.org URI requests the HTTP service.
You can associate an application with a service so that the application performs the task required by the service. For example, you can associate your preferred Web browser with the HTTP service.
To view the contents of a category of file types, click the Right-arrow next to the category name. The category expands and displays a description of each file type and the file extension that is associated with the file type.

3.4.3 Configuring Network Proxies
Click .
The Network Proxy Configuration tool lets you configure how your system connects to the Internet. You can configure the desktop to connect to a proxy server and specify the details of the server. A proxy server is a server that intercepts requests to another server and fulfills the request itself, if it can. You can specify the Domain Name Service (DNS) name or the Internet Protocol (IP) address of the proxy server. A DNS name is a unique alphabetic identifier for a computer on a network. An IP address is a unique numeric identifier for a computer on a network.

3.4.4 Managing Sessions
Click .
This module lets you manage your sessions. A session occurs between the time that you log in to the desktop environment and the time that you log out. You can set session preferences and specify which applications to start when you begin a session. You can configure sessions to save the state of applications and then restore the state when you start another session.
You can also use this preference tool to manage multiple sessions. For example, you might have a mobile session which starts applications you use most frequently when traveling, a demo session that starts applications used to present a demonstration or slide show to a customer, and a work session that uses a different set of applications when you are working in the office.
This module consists of three tabbed pages:
-
Session Options:Lets you manage multiple sessions and set preferences for the current session.
-
Current Session:Lets you specify startup order values and select restart styles for the session-managed applications in your current session.
-
Startup Programs:Lets you specify non-session-managed startup applications, which start automatically when you start a session.
Setting Session Preferences
Use the Session Options tabbed page to manage multiple sessions and set preferences for the current session.
