Content Validity. This is also a subjective measure but unlike face validity we ask whether the content of a measure covers the full domain of the content. If a researcher wanted to measure introversion they would have to first decide what constitutes a relevant domain of content for that trait.
WBFS, or Wii Backup File System, is a file system developed by Wii homebrew coder Waninkoko.[1] It uses Waninkoko's cIOS and works by creating a WBFS partition on a SD or USB device. A Wii homebrew application may then be run to dump a Wii game to the partition. The titles may then be launched using a Wii USB loader, which uses cIOS and USB 2.0 to load games from an external device.
Apple File System. Not to be confused with Apple File Service (AFS), the service implementing the Apple Filing Protocol (AFP), formerly AppleTalk Filing Protocol.

It aims to address the core issues of the existing HFS+ (also called Mac OS Extended) file system in use on these platforms today.
