现在想给这些文件重命令一下,举例
X86-zh-cn-windows2000-kb927891-x86-chs_ee51f387b97f1e615a486f8c71ac1aed589c5e7f.exe >>windows2000-kb927891-x86-chs.exe
zh-cn-msxml6-kb933579-chs-x86_380e3e565b622835162f2df7602d55c4b2caca66.exe >>msxml6-kb933579-chs-x86.exe

简单来说就是去提文件名前的X86-zh-cn-,去掉文件后的类似_89558ff3e11f488951bd38621637c05fbe562433的乱字符,本人水平有限,请那位高人帮帮忙

@echo off 

for /f "delims=" %%i in (readme.txt) do (

   set str=%%i

   setlocal enabledelayedexpansion

   if /i "!str:~0,2!"=="X8" (echo !str:~10,-45!) else (echo !str:~6,-45!)

   endlocal

)

pause

改名，自己写吧

多谢指点
