What is a txd file and how do I open a txd file?

A game texture dictionary file can be opened using the TXD Viewer software, an application developed for the PlayStation 2 gaming console, and there are many other programs developed for Microsoft Windows-based systems that can also be used to open and view the content of these game texture dictionary files. Digital bitmap images are archived and stored in a game texture dictionary file, and these small bitmap images are used as texture data implemented into many digital video gaming applications. These digital video game programs that use these game texture dictionary files as reference items are programs implemented with support for the Renderware 3D engine. These bitmap images stored in a game texture dictionary file may be processed with texture-mapping functionalities which can in turn change the visual appearance and textures of the images. The Tony Hawk's American Wasteland video game and the GTA (Grand Theft Auto) application are examples of digital video games that are implemented with support for the Renderware 3D engine as well as support for using the bitmap image content stored in these game texture dictionary files. The TXD file format is used to save these game texture dictionary files, and these files are also affixed with the .txd extension.
