RenderWare binary stream file
From Just Solve the File Format Problem
A RenderWare binary stream file (also known as a DFF file for one of its common exensions, but it appears with other file extensions in other uses) is a hierarchically structured binary file used in game animations primarily in the Grand Theft Auto series.
Possible extensions include:
- .dff (Dive File Format), for GTA model files
- .txd for texture archives
- .anm for cutscene animations in GTA III
- .rws, .bsp, .dma: Other extensions sometimes used for non-GTA games
