This week's theme: Obscure Foundation File Classes!

  1. NSFileVolume is a class that allows you to perform fundamental file system operations on volumes, such as injecting its partitions.
  1. NSFileWrapper represents nodes in the file system, such as directories known as file packages, but can also represent regular files and symbolic links.
  1. NSFileHandle provides a wrapper for file system descriptors, allowing you to perform basic file IO such as reading, writing, and locking files.
  1. NSURLProtocol allows you to implement custom loading strategies for your own protocols, so they can be used anywhere a regular NSURL is used.
