目录是否存在的检查：
BOOL FolderExist(CString strPath)
...{
WIN32_FIND_DATA wfd; BOOL rValue = FALSE; HANDLE hFind = FindFirstFile(strPath, &wfd); if ((hFind != INVALID_HANDLE_VALUE) && (wfd.dwFileAttributes & FILE_ATTRIBUTE_DIRECTORY))
...{ rValue = TRUE; 
} FindClose(hFind); return rValule;
}文件存在性检查：
BOOL FileExist(CString strFileName)...{ CFileFind fFind; return fFind.FindFile(strFileName); }
创建目录：
BOOL CreateFolder(CString strPath)...{ SECURITY_ATTRIBUTES attrib; attrib.bInheritHandle = FALSE; attrib.lpSecurityDescriptor = NULL; attrib.nLength = sizeof(SECURITY_ATTRIBUTES); //上面定义的属性可以省略。 直接return ::CreateDirectory( path, NULL); 即可 return ::CreateDirectory( strPath, &attrib);}
