Files that contain the .wtf file extension are most commonly associated with the World of Warcraft computer gaming application. These files are used to store the settings that are used by the game during a user's gameplay, such as the configuration, audio and display settings.
When a World of Warcraft (also known as WoW) player modifies the settings for his or her particular WoW interface, the WTF files that are used by the software application will also change. In some cases, the settings of the World of Warcraft game can be modified and customized by editing the WTF files themselves.
