bsp error

does anyone know why my bsp files have issues being extracted by winrar? when extracting them i get a friendly little message telling me the bsp is corrupt, usually when trying to install larger maps like the new cityway map on, i have no problem with smaller maps like prypiat, anyone got a clue?

Maybe get a different program? You could also just copy and paste the .BSP files into the map folder. If there are other things like ambient noises or props that come with it, I’m not sure what to do. I usually just improvise or get another map.
