I have a complex NSDocument with lots of files. One of those files is has a .mfst extension. If the user double-clicks one of those files, I want my app to create my NSDocument subclass, and then call a method on it to read the contents of that file, but I don't want that to be the file it then associates with the document. The actual on-disk representation is a package, and can either copy the originally-opened file contents into the package, or reference that file with an alias.
At some point, the user will have to specify a location for the "real" document package to live. Conversely, if the user double-clicks on the real document package, I want that to behave as expected.
How do I set up my Document Types and handle this scenario?
Thanks.
