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