这一个帮我做到了。它有一个日期，你可以减去想要的数量，回到过去的时间:

@echo off

set m=%date:~-7,2%
set /A m
set dateYear=%date:~-4,4%
set /A dateYear -= 2
set DATE_DIR=%date:~-10,2%.%m%.%dateYear% 

forfiles /p "C:\your\path\here\" /s /m *.* /d -%DATE_DIR% /c "cmd /c del @path /F"

pause

cmd /c del @path /F中的/F强制删除特定文件，在某些情况下，该文件可以是只读的。

dateYear是年份变量，您可以根据自己的需要更改减号

看看我对类似问题的回答:

REM del_old.bat
REM usage: del_old MM-DD-YYY
for /f "tokens=*" %%a IN ('xcopy *.* /d:%1 /L /I null') do if exist %%~nxa echo %%~nxa >> FILES_TO_KEEP.TXT
for /f "tokens=*" %%a IN ('xcopy *.* /L /I /EXCLUDE:FILES_TO_KEEP.TXT null') do if exist "%%~nxa" del "%%~nxa"

这将删除比给定日期更早的文件。我相信它可以被修改为从当前日期往回走7天。

更新:我注意到HerbCSO已经改进了上面的脚本。我建议改用他的版本。

我的脚本删除文件早于特定年份:

@REM _______ GENERATE A CMD TO DELETE FILES OLDER THAN A GIVEN YEAR
@REM _______ (given in _olderthanyear variable)
@REM _______ (you must LOCALIZE the script depending on the dir cmd console output)
@REM _______ (we assume here the following line's format "11/06/2017  15:04            58 389 SpeechToText.zip")

@set _targetdir=c:\temp
@set _olderthanyear=2017

@set _outfile1="%temp%\deleteoldfiles.1.tmp.txt"
@set _outfile2="%temp%\deleteoldfiles.2.tmp.txt"

  @if not exist "%_targetdir%" (call :process_error 1 DIR_NOT_FOUND "%_targetdir%") & (goto :end)

:main
  @dir /a-d-h-s /s /b %_targetdir%\*>%_outfile1%
  @for /F "tokens=*" %%F in ('type %_outfile1%') do @call :process_file_path "%%F" %_outfile2%
  @goto :end

:end
  @rem ___ cleanup and exit
  @if exist %_outfile1% del %_outfile1%
  @if exist %_outfile2% del %_outfile2%
  @goto :eof

:process_file_path %1 %2
  @rem ___ get date info of the %1 file path
  @dir %1 | find "/" | find ":" > %2
  @for /F "tokens=*" %%L in ('type %2') do @call :process_line "%%L" %1
  @goto :eof

:process_line %1 %2
  @rem ___ generate a del command for each file older than %_olderthanyear%
  @set _var=%1
  @rem  LOCALIZE HERE (char-offset,string-length)
  @set _fileyear=%_var:~0,4%
  @set _fileyear=%_var:~7,4%
  @set _filepath=%2
  @if %_fileyear% LSS %_olderthanyear% echo @REM %_fileyear%
  @if %_fileyear% LSS %_olderthanyear% echo @del %_filepath%
  @goto :eof

:process_error %1 %2
  @echo RC=%1 MSG=%2 %3
  @goto :eof

这没什么了不起的，但我今天需要做这样的事情，并按照预定的任务等运行它。

批处理文件，DelFilesOlderThanNDays.bat下面的示例exec w/ params:

DelFilesOlderThanNDays.bat 7 C:\dir1\dir2\dir3\logs *.log

echo off
cls
Echo(
SET keepDD=%1
SET logPath=%2 :: example C:\dir1\dir2\dir3\logs

IF [%3] EQU [] SET logFileExt=*.log & echo: file extention not specified (default set to "*.log")

IF [%1] EQU [] echo: number of days not specified? :)

更灵活的方法是使用FileTimeFilterJS.bat:

@echo off

::::::::::::::::::::::
set "_DIR=C:\Users\npocmaka\Downloads"
set "_DAYS=-5"
::::::::::::::::::::::

for /f "tokens=* delims=" %%# in ('FileTimeFilterJS.bat  "%_DIR%" -dd %_DAYS%') do (
    echo deleting  "%%~f#"
    echo del /q /f "%%~f#"
)

该脚本将允许您使用诸如日、分、秒或小时等测量。 选择weather按创建、访问或修改时间筛选文件 列出某个日期之前或之后(或两个日期之间)的文件 选择是显示文件还是dirs(或两者都显示) 递归与否

这个在7daysclean上的修改怎么样?CMD要把闰年考虑进去吗?

它可以在不到10行代码中完成!

set /a Leap=0
if (Month GEQ 2 and ((Years%4 EQL 0 and Years%100 NEQ 0) or Years%400 EQL 0)) set /a Leap=day
set /a Months=!_months!+Leap

Mofi编辑:

由于语法无效，由J.R.提供的上述条件总是计算为false。

GEQ 2月份也是错误的，因为在闰年里，只有3月到12月必须增加86400秒来增加一天，而2月则不行。

在批处理文件7天清理中考虑闰日的工作代码-仅在当前年份。Jay发布的cmd将是:

set "LeapDaySecs=0"
if %Month% LEQ 2 goto CalcMonths
set /a "LeapRule=Years%%4"
if %LeapRule% NEQ 0 goto CalcMonths
rem The other 2 rules can be ignored up to year 2100.
set /A "LeapDaySecs=day"
:CalcMonths
set /a Months=!_months!+LeapDaySecs
