如在E:\备份文件\  下有很多时间格式的目录   2022-08-12 2022-09-10 2022-09-11 2022-10-28 2022-10-29  这些目录是通过计划任务每天备份文件生成的，现在想删除30天以前的目录 ，也就是说要删除 2022-10-29以前的所有目录，怎么写批处理。
原先做的是每次在备份后自动删除前30天那一天的备份，那是因为电脑天天开着（给服务器备份mysql数据库用），可以删除30天前每天的备份，但是用来备份工作文件的话，电脑不是每天开着的话，会导到前边的目录会遗留下来，而不能自动删除掉，需手工再去删。

谢谢你的指点。

我试了这个命令，它是以目录的修改日期来判断，而删除日期目录内的子目录，在有残留目录的时候，遍历时间很长，而且会显示报错“错误：系统找不到指定的文件。”
测试中还发现这命令还有个缺点，一旦它自动地删除了最下级目录的文件或目录（目录内还有多级子目录和文件的存在），其父目录的修改时间就会改变，继而就不再删除父目录了。命令执行结束后，还有好多目录还是都存在着。

我设想的是直接根据目录的内容（就是日期形式，用日期格式来做运算）来判断，继而直接rd掉这个日期格式目录（最外层的这个目录）

rem 下面为只删除指定目录下的子文件夹和文件，不删除本身目录 ，文件夹名称后面不要添加 \ 字符
set "SrcDir=E:\0006\222"
rem 下面为指定天数之前
set DaysAgo=7

::说明：彻底删除指定路径下指定天数之前（以文件的最后修改日期为准）的文件夹和文件。是彻底删除，并不会出现在回收站里。
forfiles /p %SrcDir% /s /m "*" /d -%DaysAgo% /c "cmd /c del /f /q @path & RD /S /Q @path"

   我使用了第五个方案的代码，没有动作，请帮忙分析下原因。

现目录下的文件如下：
G:\beifen 的目录

2022-11-28  23:46    <DIR>          .
2022-11-28  23:46    <DIR>          ..

生成的DstDate.vbs 内容为：

  2. @echo off
  3. @rem 保存为ANSI格式
  4. set "SrcDir=E:\0006\222"
  5. set "DaysAgo=7"
  6. pushd "%SrcDir%"

使用以上代码进行测试，发现它会遍历当前目录下的所有目录，并把目录中或下层子目录（下下层）的文件或目录删了一部分
备份了当天的，然后测试，

文件备份后 “2022-12-02” 的目录属性
527 MB (552,927,232 字节)
1,273 个文件，204 个文件夹

运行代码后 2022-12-02” 的目录属性
369 MB (386,961,408 字节)
154 个文件，56 个文件夹

也就是说没有进行日期的判断  （备份产生的这个日期文件夹都存在未被删除）

如果不介意第3方工具find64.exe（ http://bcn.bathome.net/tool/find64.exe ）
可用如下脚本实现：

  2. @echo off
  3. @rem 保存为ANSI格式
  4. set "SrcDir=G:\文件备份"
  5. set "DaysAgo=30"
  6. pushd "%SrcDir%"
  7. find64 -type f -ctime +%DaysAgo% -delete
  8. find64 -type d -empty -delete
  9. popd

假设当前目录下有多个一级子目录，名如 2022-09-11，2022-10-28，...
指定一个期限，格式如 2022-09-11，其中前导零不能省略，
则如下代码被运行后，会删除早于或等于 2022-09-11 的全部一级子目录。
备注》dir /b/ad/tc/od 参数中的 tc 表示按目录创建日期排序 改为 tw 则表示按目录最后修改日期排序，od 表示升序 o-d 表示降序，本代码须用 od。

楼主可先用模拟样本试用一下。删除目录还须慎重。


  2. @echo off
  3. set/p "qd=指定目录的删除期限(格式如2022-09-01 早于或等于此限均被删除): "
  4. if not defined qd exit/b
  5. setlocal enabledelayedexpansion
  6. for /f "delims=" %%F in ('dir /b/ad/tc/od 20??-??-??') do (
  7.     set "d8=%%~nF"
  8.     if "!d8!" leq "%qd%" (rd /s /q "%%F") else (endlocal &exit/b)
  9. )
  10. endlocal &exit/b

如果不用tc或/tw排序，代码还可简化如下...

  2. @echo off
  3. set "qd=" &set/p "qd=指定目录的删除期限(格式如2022-09-01 早于或等于此限均被删除): "
  4. if not defined qd exit/b
  5. for /f "delims=" %%F in ('dir /b/ad/od 20??-??-??') do (
  6.     if "%%~nF" leq "%qd%" (rd /s /q "%%F")
  7. )
  8. exit/b

    这个方案可以了，不过有个问题，有几个目录是2021-06-23  2021-07-23 2021-07-24 的目录，它不进行删除，其他我设置的目录可以删掉



  4. G:\beifen>rem @echo off

  6. G:\beifen>REM ----------------------------------------------------------------------------------------

  8. G:\beifen>REM 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。

  10. G:\beifen>REM 如果演示结果无误，把rd前面的echo去掉，即可实现真正删除。

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

  14. G:\beifen>REM ----------------------------------------------------------------------------------------

  16. G:\beifen>REM 指定待删除文件夹的存放路径

  18. G:\beifen>set "SrcDir=G:\beifen"

  20. G:\beifen>REM 指定天数

  22. G:\beifen>set "DaysAgo=5"

  24. G:\beifen>echo LastDate=date()-5 1>"C:\Users\ADMINI~1\AppData\Local\Temp\DstDate.vbs"
