  采用的是MFC，如果需要移植到SDK，只要把CString换成相应类型即可。
  代码比较简单，只简单做一下解释：
  BOOL DeleteDirectory(const CString szDir)
  {
   CString szFindDir=szDir;
   if(szFindDir.Right(1)!="//")
   {
    szFindDir+="//"; 
   }
   szFindDir+="*.*";
  
   WIN32_FIND_DATA fd;
   HANDLE hFind;
   hFind=FindFirstFile(szFindDir,&fd);
   if(hFind!=INVALID_HANDLE_VALUE)
   {
    do{
     if(fd.dwFileAttributes==FILE_ATTRIBUTE_DIRECTORY)
     {  
      //it must be directory,get into
      DeleteDirectory(szDir+"//"+fd.cFileName);  
     }
     else
     { 
      //it is file ,delete it
      if(DeleteFile(szDir+"//"+fd.cFileName)==FALSE)
      {
       return FALSE;
      }
     }
  
    }while(FindNextFile(hFind,&fd));
   }
  
   //if you donot close the handle,the next step of Removing Directory would failed
   CloseHandle(hFind);
   //the root directory must be empty ,so remove it
   if(RemoveDirectory(szDir)==FALSE)
   {
    return FALSE;
   }
  
   return TRUE;
  }                          
                      
  
  由此也可引出一个判断目录是否为空的代码，也比较简单，如下：
  BOOL IsDirEmpty(const CString szDir)
  {
   CString szFindDir=szDir;
   if(szFindDir.Right(1)!="//")
   {
    szFindDir+="//"; 
   }
   szFindDir+="*.*";
  
   WIN32_FIND_DATA fd;
   HANDLE hFind;
   hFind=FindFirstFile(szFindDir,&fd);
   if(hFind!=INVALID_HANDLE_VALUE)
   {
    return FALSE;
   }
   else
   {
    //it is empty
    return TRUE;
   }
  }
