【方案一】BAT + REG + VBS
- @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

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

【方案三】BAT + VBS
- @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
- @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
