??采用的是MFC，如果需要移植到SDK，只要把CString換成相應類型即可。
??代碼比較簡單，只簡單做一下解釋：
??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;
??}??????????????????????????

??
??由此也可引出一個判斷目錄是否為空的代碼，也比較簡單，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;
???}
??}
