[文件操作] 如何用批处理操作30分钟前创建的文件？

@echo off&setlocal enabledelayedexpansion
for /f "tokens=1,2 delims=:" %%a in ('echo.%time% /t') do set /a nowt=0x%%a*60+0x%%b
for /f %%a in ('dir /b e:\test') do ( 
       set tm=%%~ta
       for /f "tokens=2,3 delims=: " %%b in ('echo.!tm!')do set /a tout=nowt-^(0x%%b*60+0x%%c^)
       if "!nowt!" leq 30 move %%~fa e:\test2
)
