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;
}
}
