#include <iostream>
#import "scrrun.dll" raw_interfaces_only 
int main()
{
CoInitialize(NULL);
{
try
{
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;
std::cout<<"COM error occurred,source:"<<(LPCTSTR)bstrSource<<std::endl;
std::cout<<"Description:"<<(LPCTSTR)bstrDescription<<std::endl;
}
}
CoUninitialize();
return 0;
}

Answer 2

WIN32_FIND_DATA fd;
HANDLE hFile = FindFirstFile("*.*", &fd);
if(hFile)
{
do{
if( (fd.dwFileAttributes & FILE_ATTRIBUTE_DIRECTORY)!= FILE_ATTRIBUTE_DIRECTORY)
{
fd.nFileSizeLow //文件大小的低32位
fd.nFileSizeHigh //文件大小的高32位位
}
}while(FindNextFile(hFile, &fd));
FindClose(hFile);
}//if(hFile)
