DDS
The Microsoft DirectDraw Surface (.dds) file format.

Oblivion employs the DDS format for textures. The Microsoft DirectDraw Surface (.dds) file format stores textures and cubic environment maps, with or without mipmaps. It was introduced with DirectX 7.0.

Although the format is not natively supported by most graphic editing applications, there are a number of Tools designed to handle the format.
