| Action defaults files / Using action defaults files | |
Global action defaults are defined in an XML file with the 4ad extension. By default, the runtime system searches for a file named default.4ad in the current directory. If the file does not exist, it searches in the directories defined by the FGLRESOURCEPATH (or DBPATH) environment variable. If no file was found using the environment variable(s), standard action default settings are loaded from the FGLDIR/lib/default.4ad file.
Action defaults files usage is related to action configuration concepts. For more details, see Configuring actions.
