Notes about the TXD file extension:
Incorrect file associations could be the result of underlying issues within your PC system. As such it is highly recommended to scan your PC for invalid registry entries, unused processes and other unfavourable system settings to identify slowdown issues.
The TXD file type is primarily associated with 'Renderware' by Criterion Software. There are different versions of TXDs, they differ from the system they are used on and the Renderware version that is used. TXDs contain the textures of a DFF 3D model. These files are part of the Renderware engine. There are many types of software that will create, import and export these models. Some of these are in the Associate Links.
