It sounds like you want your file format to be what is known as a “package”. It’s a directory, but is (mostly) presented as a single file.
NSFileWrapper is an API for working with files, it does not directly control whether something is a package or not. It just happens to be the most convenient API in Cocoa for working with packages and documents, and so NSDocument has built in support for that.
