RenderWare binary stream files are hierarchically structured binary data files used by the RenderWare 3.x graphics engine utilized by Rockstar North for their GTA III trilogy (only on PC, PS2 and XBOX, not PSP!) and related games (Manhunt, Bully). GTA's model files use the file extension .dff and texture archives use .txd. Other possible extensions, not used by the GTA games, are .rws, .bsp and .dma. GTA3 does use .anm for some of its cutscene animations, but it is the only GTA to do so.
