MFC 文件I/O和串行化

void EnumerateFolders ()
{
    WIN32_FIND_DATA fd;
    HANDLE hFind = ::FindFirstFile (_T ("*.*"), &fd);

    if (hFind != INVALID_HANDLE_VALUE) {
        do {
            if (fd.dwFileAttributes & FILE_ATTRIBUTE_DIRECTORY) {
                CString name = fd.cFileName;
                if (name != _T (".") && name != _T ("..")) {
                    TRACE (_T ("%s\n"), fd.cFileName);
                    ::SetCurrentDirectory (fd.cFileName);
                    EnumerateFolders ();
                    ::SetCurrentDirectory (_T (".."));
                }
            }
        } while (::FindNextFile (hFind, &fd));

}
//比如说枚举E:\svn文件夹，不过可能会导致栈溢出
::SetCurrentDirectory(_T("e:\\svn"));
