对纯DOS不太熟悉，请教几个问题：
请问纯DOS方式下可以使用WMIC吗？你给的这段代码在纯DOS方式下能得到正确结果吗？你是用的纯DOS是哪个版本呢？

@echo off

setlocal enabledelayedexpansion

set bb=

for %%i in (C D E F G H I J K L M N O P Q R S T U V W X Y Z) do (

   set aa=

   for /f "tokens=*" %%a in ('dir %%i:\#### 2^>^&1^|findstr /I "specified 指"') do set aa=%%a

   if not "!aa!"=="" (  

      echo !bb!:

      goto :eof

   )

   set bb=%%i

)

xp下的结果与dos下的，是毫不相干的两码事。
不知楼主说得是啥，想要干嘛。呵呵。

这样U盘也算在内.

echo %doslastdrive%

dos下的最后盘符，不到dos下去确定，而在window下确定，是不合理的。
