As far as i know - .DDS file is an image/graphic/texture file, so you can not "extract" it. I am not 100% sure about this, since some programs might use their own file extentions.

"The DDS file type is primarily associated with 'DirectX (Multiple Versions)' by Microsoft Corporation.
The Microsoft DirectDraw Surface (DDS) file format is used to store textures and cubic environment maps, both with and without mipmap levels.

This format can store uncompressed and compressed pixel formats, and is the preferred file format for storing DXTn compressed data.

This file format is supported by the Microsoft DirectX Texture tool (DXTex Tool), as well as some third party tools, and by the Direct3D extensions (D3DX) library."
