If you are having Windows XP the saves are in the folder:
C:\Documents and Settings\ %username% \Local Settings\Application Data\Divinity 2\Savegames

If you are having Windows Vista or Windows 7 the saves are in the folder:
C:\Users\ %username% \AppData\Local\Divinity 2\Savegames

If the AppData folder doesn’t appear it’s because it’s hidden.
