[其他] 批处理怎样实现删除n天以前类似yyyymmdd这样的文件夹及其文件？

@echo off
rem 指定待删除文件夹的存放路径
set SrcDir=F:\201221test\smppbillstore
rem 指定天数
set DaysAgo=1

>"%temp%/DstDate.vbs" echo LastDate=date()-%DaysAgo%
>>"%temp%/DstDate.vbs" echo FmtDate=right(year(LastDate),4) ^& right("0" ^& month(LastDate),2) ^& right("0" ^& day(LastDate),2)
>>"%temp%/DstDate.vbs" echo wscript.echo FmtDate
for /f %%a in ('cscript /nologo "%temp%/DstDate.vbs"') do (
  set "DstDate=%%a"
)
set DstDate=%DstDate:~0,4%-%DstDate:~4,2%-%DstDate:~6,2%

setlocal enabledelayedexpansion
for /d  %%a in ("%SrcDir%/*.*") do (
  if "%%~ta" leq "%DstDate%" (
    set "FolderDate=%%~na"
    set "FolderDate=!FolderDate:~8,10!"
    if "!FolderDate!" leq "%DstDate%" (
        cd %SrcDir%
        if exist "%%a/" (
            echo rd /s /q "%%a"
        )
    )
  )
)
endlocal
pause
