FSFileSystem
An abstract base class for implementing a full-featured file system.
Declaration
@interface FSFileSystem : NSObjectOverview
FSFileSystem is a full-featured file system, which works with one or more FSResource instances and presents one or more FSVolume references to callers.
Implement your app extension by providing a subclass of FSFileSystem as a delegate object. Your delegate also needs to implement the FSFileSystemOperations protocol so that it can probe, load, and unload resources.
