At run time, your package will obtain the value for the Directory property from the VarFolderName parameter.
To verify that the package updates the Directory property with the new value during run time, simply execute the package. Because only three sample data files were copied to the new directory, the data flow will run only three times, rather than iterate through the 14 files in the original folder.
