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.
What is a MDF file? Files given the .mdf extension contain a disc image of the information that has been saved on a CD or DVD. MDF files are similar to ISO files, but they are saved in a different format. In order for the DVD or CD data to be played back properly, the MDF file must be saved with an associated MDS file.
