File with a SCS extension contains a game save file – a city along with its community, created during a game of SimCity Societies or SimCity Societies Destinations. Default game save files storing directory is My Documents/Simcity Societies/User Data/[player_name]/Save Games.

The above mentioned games, which share the type of save file, enable simulation of creation of a city and development of a community. SCS files, along with the related TGA files containing minimaps, are used to save state of a developing city and to share it with friends.
