This class is used to represent a file, or a set of files contained in a file package, as a single unit of information in a document or application. NSFileWrapper is often used in conjunction with subclasses of NSDocument as a means of conveniently managing a document's data. This class provides functionality that allows clients to edit file attributes and perform file operations. Additionally, clients may assign an icon to represent the file wrapper object in dragging operations.
