A preference file is an ASCII file that configures the application or its clients. It specifies default user settings such as the order in which colors are assigned, the default printer, default page layout, etc... A standard preference file can be created in the program installation directory which is executed every time a license is activated. An additional preference file can be created in your working directory that contains personal settings that either overwrite the standard preference file or are added to the existing settings in the standard preference file.
