What is a Z2S file? Saved game file created with Zoo Tycoon, a zoo simulation game that allows players to operate zoos. It contains saved game progress so that the player can resume the game at another time. Z2S should be stored in the "Saved Games" folder within the Zoo Tycoon directory.

More Information Zoo Tycoon 2 was released in 2004 as a sequel to the original Zoo Tycoon. In the game you can choose the type of zoo to create and build animal exhibits, restaurants, bathrooms, and other facilities to be successful. As you progress through the game you unlock new features such as exotic animals and newer facilities. The Z2S file allows you to save all of your progress so you do not have to start from the beginning every time you play.
