Hi Riccardo,
this make no sense to me.
If with "shape file" you actually mean "ESRI Shapefile" (*.shp), then, 
as previously written, an ESRI Shapefile polygon layer is always a 
MultiPolygon layer which can always stores multi-part geometries. It is 
not possible to create an ESRI Shapefile polygon layer that can store 
only single-part geometries.

Maybe with "shape file" do you mean a vector layer of a format other 
then "ESRI Shapefile"?

Best regards.
