Resource files

Resource files are containers that a development system uses to pack together sundry data that the operating system uses to represent a program, these can be icons, forms, GUI elements, bitmaps, sounds and so on, the OS can have them as external files like with the Apple Macintosh or separate files that are compiled into the executable (exe or dll) a la Microsoft Windows.
