OS X runtime application package (FileMaker Pro Advanced)
The Developer Utilities generate a runtime application package for OS X. The package will have the name that you give to your runtime solution. The runtime application package contains the core resources and code required for running the application. The contents of the package should not be altered, except to remove the language resource files. For more information, see Distributing runtime solutions (FileMaker Pro Advanced).
The package contains a Contents folder, which has information on the package and the Frameworks, OS X, and Resources folders. The Resources folder includes the language resources folders (*.lproj). The package can be opened by using the Show Package Contents command.
The Extensions folder accompanies OS X package and contains the Dictionaries folder. The Dictionaries folder contains dictionary files (*.mpr) for all of the languages supported. The Dictionaries folder also contains a file for the user spelling dictionary (User.upr).
