What is a WTD file?
Texture file used by Grand Theft Auto IV (GTA4), an action/adventure game; used for texture mapping and contains a two-dimensional graphic that gives the surface appearance to a 3D object in the game; saved in the \Rockstar\Games\Grand Theft Auto IV\pc\textures\ directory.
WTD files can be edited by SparkIV or OpenIV, but the texture editing and importing process is generally only for advanced users.
