The "Saved Games" folder can actually be moved outside of %USERPROFILE% and put anywhere, on any hard drive.Try to put "%USERPROFILE%\Saved Games" as location in explorer. The "Saved Games" part could be localised but should work in it's native form (for me it says "Gespeicherte Spiele").
You can use Win32 API SHGetKnownFolderPath with parameter of FOLDERID_SavedGames
