In Vista / Win 7 the saves are in the folder
C:\Users\ %username% \AppData\Local\Divinity 2\Savegames
and in case someone finds this topic in a search, in XP the location is
C:\Documents and Settings\ %username% \Local Settings\Application Data\Divinity 2\Savegames
You may need to set Windows Explorer to show hidden files and folders. That is probably why the search failed, as well, since you ned to specifically set Windows Search to check in hidden folders in the advanced options.
