【方案一】BAT + REG + VBS

代码如下:

@echo off

::演示：删除指定路径下指定天数之前（以文件夹的最后修改日期为准）的文件夹。

::如果演示结果无误，把rd前面的echo去掉，即可实现真正删除。

::本例调用了临时VBS代码进行日期计算

::本例为兼容不同的日期格式，调用reg命令（XP系统自带）统一设置日期格式，

::处理完毕之后再把日期格式恢复成原来的状态。

rem 指定待删除文件夹的存放路径

set SrcDir=C:/Test

rem 指定天数

set DaysAgo=1

for /f "skip=2 delims=" %%a in ('reg query "HKEY_CURRENT_USER/Control Panel/International" /v sShortDate') do (

    set "RegDateOld=%%a"

)

set RegDateOld=%RegDateOld:~-8%

reg add "HKEY_CURRENT_USER/Control Panel/International" /v sShortDate /t REG_SZ /d yyyy-M-d /f>nul

>"%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%

for /d    %%a in ("%SrcDir%/*.*") do (

    if "%%~ta" leq "%DstDate%" (

        if exist "%%a/"

            echo rd /s /q "%%a"

        )

    )

)

reg add "HKEY_CURRENT_USER/Control Panel/International" /v sShortDate /t REG_SZ /d %RegDateOld% /f>nul

pause

【方案二】BAT + REG + Ritchie Lawrence 日期函数

代码如下:

@echo off

::演示：删除指定路径下指定天数之前（以文件夹的最后修改日期为准）的文件夹。

::如果演示结果无误，把rd前面的echo去掉，即可实现真正删除。

::本例调用了 Ritchie Lawrence 的日期函数进行日期计算

::日期转换的核心算法请参考http://bbs.bathome.cn/thread-3056-1-1.html

::本例为兼容不同的日期格式，调用reg命令（XP系统自带）统一设置日期格式，

::处理完毕之后再把日期格式恢复成原来的状态。

rem 指定待删除文件夹的存放路径

set SrcDir=C:/Test

rem 指定天数

set DaysAgo=1

for /f "skip=2 delims=" %%a in ('reg query "HKEY_CURRENT_USER/Control Panel/International" /v sShortDate') do (

set /a PassDays-=%DaysAgo%

call :DaysToDate %PassDays% DstYear DstMonth DstDay

set DstDate=%DstYear%%DstMonth%%DstDay%

set DstDate=%DstDate:~0,4%-%DstDate:~4,2%-%DstDate:~6,2%

for /d    %%a in ("%SrcDir%/*.*") do (

    if "%%~ta" leq "%DstDate%" (

        if exist "%%a/"

            echo rd /s /q "%%a"

        )

    )

)

【方案三】BAT + VBS

代码如下:

@echo off

::演示：删除指定路径下指定天数之前（以文件夹的最后修改日期为准）的文件夹。

::如果演示结果无误，把rd前面的echo去掉，即可实现真正删除。

::本例调用了临时VBS代码进行日期计算，并统一设置系统日期格式，处理完毕

::之后再把日期格式恢复成原来的状态。摆脱了对reg命令（XP系统自带）的依赖。

rem 指定待删除文件夹的存放路径

set SrcDir=C:/test

rem 指定天数

set DaysAgo=1

>"%temp%/BackupDate.vbs" echo Set WshShell = WScript.CreateObject("WScript.Shell")

>>"%temp%/BackupDate.vbs" echo WScript.Echo WshShell.RegRead ("HKEY_CURRENT_USER/Control Panel/International/sShortDate")

for /f %%a in ('cscript /nologo "%temp%/BackupDate.vbs"') do (

    set "RegDateOld=%%a"

)

>"%temp%/UnifyDate.vbs" echo Set WshShell = WScript.CreateObject("WScript.Shell")

>>"%temp%/UnifyDate.vbs" echo WshShell.RegWrite "HKEY_CURRENT_USER/Control Panel/International/sShortDate", "yyyy-M-d", "REG_SZ"

cscript /nologo "%temp%/UnifyDate.vbs"

>"%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%

for /d    %%a in ("%SrcDir%/*.*") do (

    if "%%~ta" leq "%DstDate%" (

        if exist "%%a/"

            echo rd /s /q "%%a"

        )

    )

)

>"%temp%/RecoverDate.vbs" echo Set WshShell = WScript.CreateObject("WScript.Shell")

>>"%temp%/RecoverDate.vbs" echo WshShell.RegWrite "HKEY_CURRENT_USER/Control Panel/International/sShortDate", "%RegDateOld%", "REG_SZ"

cscript /nologo "%temp%/RecoverDate.vbs"

pause

【方案四】字符串截取

代码如下:

@echo off

::演示：删除指定路径下指定天数之前（以文件夹名中包含的日期字符串为准）的文件夹。

::如果演示结果无误，把rd前面的echo去掉，即可实现真正删除。

::本例假设文件夹名中包含的日期字符串（比如：Archive-2009-12-25）

rem 指定待删除文件夹的存放路径

set SrcDir=C:/test

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%" (

        if exist "%%a/" (

            echo rd /s /q "%%a"

        )

    )

  )

)

endlocal

pause
