Scripting::IFileSystem3Ptr fs;
fs.CreateInstance(__uuidof(Scripting::FileSystemObject));
Scripting::IFolderPtr folder;
fs->GetFolder(_bstr_t("c:\\temp"),&folder);
_variant_t vsize;folder->get_Size(&vsize);
std::cout<<"c:\\temp size:"<<(long)vsize<<" bytes"<<std::endl;
}
catch(_com_error &e)

_bstr_t bstrSource(e.Source());
_bstr_t bstrDescription(e.Description());
std::cout<<"Get directory size via FileSystemObject, by masterz"<<std::endl;
