I am reading a document in the format of the old version of my app and converting it to a new format. The old version is not a document at all but is a fixed data file in /Application Support/MyApp/
MyDocument *untitledDoc = [[NSDocumentController sharedDocumentController] makeDocumentForURL:nil withContentsOfURL:fileURL ofType:kApplicationDocumentType error:&error]; if (untitledDoc) { [untitledDoc makeWindowControllers]; [untitledDoc showWindows]; [untitledDoc setFileURL:nil]; [[NSDocumentController sharedDocumentController] addDocument:(NSDocument *)untitledDoc]; } This works fine and I am able to migrate the data into a real NSDocument subclass. However, if I close the window (thus closing the document) and choose to not save, the file package at fileURL is deleted. Yikes! How can I completely disassociate the fileURL from the new document that I created. I want to treat fileURL as a template or stationary that is only read from, and never written to. [untitledDoc setFileURL:nil] does not seem to work to disassociate the document from the source file.
