What are preference files?
Preferences files are those storing all sorts of application-specific information, including the rules or parameters that show you how the application works. You can find the preference files in the applications contents. Usually, preference files are located in ~/Library/preferences/. The name of an application’s preference files is usually in the format “com. [the name of the software vendor]. [application name].plist”. Other preference files just end in the application name, without the “com” prefix.
