This program lets you EXPORT images into .dds format, which is used in Halo and many other games. It does not READ .dds files however. If you need to open .dds files, try Graphic Converter for Mac (sketchy support for DDS, but lets you convert) or Windows Texture Viewer for PC (basic DDS viewing capabilities, doesn't let you convert). If you use Windows, also see the NVIDIA Developer Zone legacy tools page and their plugins for Photoshop (Windows version only).
