You mean "transfer from chapter 1 to 2"? you don't need to. It is automatically done. The game should read me by default. Now, if you mean how to move from one machine to another, you can find your saved files at:
C:\Users\<your user name>\AppData\Local\ZIsland
Replace <your user name> with your windows user name and you will find a "Saved" folder which contains your saved data. Hope this helps
