求一个BAT文件，因为在PE里运行，所以不能用脚本
要求
如果 C 盘大于50G 就运行a.exe，否则就运行b.exe

BAT算不算脚本？
@echo off
set /p drive=你想知道那个分区的容量？
if "%drive%" equ "" (
goto :eof
) else (
set drive=%drive:~0,1%
)
set drive=%drive::=%
set drive=%drive:\=%
set total=
for /f "tokens=2 delims==" %%a in ('wmic LogicalDisk where "DeviceID='%drive%:'" get Size /value') do set total=%%a
echo 总空间：%total%
set /p drive=你想知道那个分区的容量？
if "%drive%" equ "" (
goto :eof
) else (
set drive=%drive:~0,1%
)
set drive=%drive::=%
set drive=%drive:\=%
set total=
for /f "tokens=2 delims==" %%a in ('wmic LogicalDisk where "DeviceID='%drive%:'" get Size /value') do set total=%%a
echo 总空间：%total%

看不懂了，能解释一下吗？
我的意思是
IF C盘>50G
a.exe
else
b.exe

BAT算脚本，我写错了，我说不能用VBS和JS因为我试了一下，在PE里报错，虽然官方说PE支持VBS

HAT兄的代码在PE通不过，主要是PE下无“wmic”。
作者: terse 时间: 2008-7-16 00:39
查整个容量 还是可用容量呢 如查到可用容量可行不
作者: HAT 时间: 2008-7-16 09:39
楼主的需求是查询整个容量，呵呵。

我要求查整个C盘的容量
