Yes. You know, on a Macintosh, files are really split in 2 files, a data
fork and a resource fork. The resource fork was created for the Macintosh
introduction in 1984. The idea for the resource fork was to have a set of
known standards for resources that relate to a file. Apple did introduce
quite a few resource types and all developers did follow. That's why almost
all applications, for instance, have 'code', 'dlog', 'menu', etc. resources
types, and that's why you can open those resources in ResEdit (or
Resorcerer). For example, to define a window, Apple decided on a structure
and named it 'WIND'. So, the resource manager on the Mac can access that
structure and draw the window for the application. That was one of the
factor that originally contributed to the consistency across all
applications on the Macintosh. Another good thing was that since a lot of
the code to create thingies from those resources was in the Macintosh ROM,
the compiled applications didn't have to include the compile code to handle
those resources, resulting in smaller applications on disk.
