DDT files are used to extend the standard game database for retaining and loading custom players into team rosters.

File Type 4 Age of Mythology Textures File
Developer by: Microsoft Category: Raster Image Files Format: Binary

Graphics file used by Age of Mythology (AOM), a real-time strategy game; usually bundled inside a .BAR file and contains textures that are applied to 3D game models; used for texturizing objects such as heroes, icons, terrain objects, and army units.

DDT files can be extracted from a BAR file and converted to a .BMP format using AOM Edit, which is also called AOMed. Once extracted they may be edited using any image editor and then converted back into the DDT format using AOM Edit.

DDT files support multiple resolutions, but the dimensions of the graphic must be a power of two. For example, a 100x100 texture can use the sizes 200x200 and 400x400, but not 300x300.
