Game file used by VirtualBus (vBus), a free bus driving simulation game; contains a map that specifies roads, vehicles, traffic signs, buildings, and landscape objects such as trees and bushes; represents the 3D world that the player drives the bus in.
MS1 files are stored in the \Maps\ directory within the VirtualBus installation. If you download an MS1 file, it should be saved to this directory.
