Batch file to delete files older than N days

Question

I am looking for a way to delete all files older than 7 days in a batch file   I ve searched around the web  and found some examples with hundreds of lines of code  and others that required installing extra command line utilities to accomplish the task   Similar things can be done in BASH in just a couple lines of code  It seems that something at least remotely easy could be done for batch files in Windows  I m looking for a solution that works in a standard Windows command prompt  without any extra utilities  Please no PowerShell or Cygwin either

For windows 2012 R2 the following would work:

    forfiles /p "c:\FOLDERpath" /d -30 /c "cmd /c del @path"

to see the files which will be deleted use this

    forfiles /p "c:\FOLDERpath" /d -30 /c "cmd /c echo @path @fdate"

This one did it for me  It works with a date and you can substract the wanted amount in years to go back in time    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   the  F in the cmd  c del  path  F forces the specific file to be deleted in some the cases the file can be read-only   the dateYear is the year Variable and there you can change the substract to your own needs

Use forfiles    There are different versions  Early ones use unix style parameters    My version  for server 2000 - note no space after switches -   forfiles -p C  what ever  -s -m    -d lt number of days gt  -c cmd  c del  path    To add forfiles to XP  get the exe from ftp   ftp microsoft com ResKit y2kfix x86   and add it to C  WINDOWS system32

ROBOCOPY works great for me   Originally suggested my Iman   But instead of moving the files folders to a temporary directory then deleting the contents of the temporary folder  move the files to the trash       This is is a few lines of my backup batch file for example   SET FilesToClean1 C  Users pauls12 Temp SET FilesToClean2 C  Users pauls12 Desktop 1616 - Champlain Engineering CAD Backups  SET RecycleBin C   Recycle Bin S-1-5-21-1480896384-1411656790-2242726676-748474  robocopy   FilesToClean1     RecycleBin    mov  MINLAD 15  XA SH  NC  NDL  NJH  NS  NP  NJS robocopy   FilesToClean2     RecycleBin    mov  MINLAD 30  XA SH  NC  NDL  NJH  NS  NP  NJS   It cleans anything older than 15 days out of my  Temp  folder and 30 days for anything in my AutoCAD backup folder   I use variables because the line can get quite long and I can reuse them for other locations   You just need to find the dos path to your recycle bin associated with your login   This is on a work computer for me and it works   I understand that some of you may have more restrictive rights but give it a try anyway    Search Google for explanations on the ROBOCOPY parameters   Cheers

More flexible way is to use FileTimeFilterJS bat   echo off                         set  quot  DIR C  Users npocmaka Downloads quot  set  quot  DAYS -5 quot                          for  f  quot tokens   delims  quot      in   FileTimeFilterJS bat   quot   DIR  quot  -dd   DAYS    do       echo deleting   quot    f  quot      echo del  q  f  quot    f  quot     The script will allow you to use measurements like days  minutes  seconds or hours  To choose weather to filter the files by time of creation  access or modification To list files before or after a certain date  or between two dates  To choose if to show files or dirs  or both  To be recursive or not

forfiles  p  v    s  m      d -3  c  cmd  c del  path    You should do  d -3  3 days earlier  This works fine for me  So all the complicated batches could be in the trash bin  Also forfiles don t support UNC paths  so make a network connection to a specific drive

There are very often relative date time related questions to solve with batch file  But command line interpreter cmd exe has no function for date time calculations  Lots of good working solutions using additional console applications or scripts have been posted already here  on other pages of Stack Overflow and on other websites  Common for operations based on date time is the requirement to convert a date time string to seconds since a determined day  Very common is 1970-01-01 00 00 00 UTC  But any later day could be also used depending on the date range required to support for a specific task  Jay posted 7daysclean cmd containing a fast  quot date to seconds quot  solution for command line interpreter cmd exe  But it does not take leap years correct into account  J R  posted an add-on for taking leap day in current year into account  but ignoring the other leap years since base year  i e  since 1970  I use since 20 years static tables  arrays  created once with a small C function for quickly getting the number of days including leap days from 1970-01-01 in date time conversion functions in my applications written in C C    This very fast table method can be used also in batch code using FOR command  So I decided to code the batch subroutine GetSeconds which calculates the number of seconds since 1970-01-01 00 00 00 UTC for a date time string passed to this routine  Note  Leap seconds are not taken into account as the Windows file systems also do not support leap seconds  First  the tables   Days since 1970-01-01 00 00 00 UTC for each year including leap days  1970 -

the date string without the 3 letters of weekday abbreviation and the separating space character  Alternatively following could be used to pass current date in correct format  call  GetSeconds  quot  DATE  -10   TIME  quot   Now the last 10 characters from date string are passed to function GetSeconds and therefore it does not matter if date string of environment variable DATE is with or without weekday as long as day and month are always with 2 digits in expected order  i e  in format dd mm yyyy  or dd mm yyyy  Here is the batch code with explaining comments which just outputs which file to delete and which file to keep in C  Temp folder tree  see code of first FOR loop   echo off setlocal EnableExtensions DisableDelayedExpansion rem Get seconds since 1970-01-01 for current date and time  call  GetSeconds  quot  DATE   TIME  quot  rem Subtract seconds for 7 days from seconds value  set  A  quot LastWeek Seconds-7 86400 quot   rem For each file in each subdirectory of C  Temp get last modification date rem  without seconds -

My command is  forfiles -p  d  logs  -s -m  log -d-15 -c cmd  c del  PATH  FILE      PATH - is just path in my case  so I had to use  PATH  FILE  also forfiles    not working for me too  but forfiles  without      worked fine   And the only question I have  how to add multiple mask  for example   log  bak     All this regarding forfiles exe that I downloaded here  on win XP   But if you are using Windows server forfiles exe should be already there and it is differs from ftp version  That is why I should modify command    For Windows Server 2003 I m using this command   forfiles -p  d  Backup  -s -m   log -d -15 -c  cmd  c del  PATH

You might be able to pull this off  You can take a look at this question  for a simpler example  The complexity comes  when you start comparing the dates  It may be easy to tell if the date is greater or not  but there are many situations to consider if you need to actually get the difference between two dates   In other words - don t try to invent this  unless you really can t use the third party tools

I think e James s answer is good since it works with unmodified versions of Windows as early as Windows 2000 SP4  and possibly earlier   but it required writing to an external file  Here is a modified version that does not create an external text file while maintaining the compatibility   REM del old cmd REM usage  del old MM-DD-YYYY setlocal enabledelayedexpansion for  f  tokens      a IN   xcopy      d  1  L  I null   do  if exist     nxa  set  excludefiles  excludefiles      nxa    for  f  tokens      a IN   dir  b   do    echo   excludefiles   FINDSTR  C      a    gt nul    if exist     nxa  DEL  F  Q    a  gt nul 2 gt  amp 1    To be true to the original question  here it is in a script that does ALL the math for you if you call it with the number of days as the parameter   REM del old compute cmd REM usage  del old compute N setlocal enabledelayedexpansion set  a days  1 amp set cur y  DATE  10 4  amp set cur m  DATE  4 2  amp set cur d  DATE  7 2  for  f  tokens 1 delims      a in   set cur    do if     a  0 1     0  set  a   a    a  1 1  0 set mo 2 28 amp set  a leapyear cur y 10 4 if  leapyear  -1  equ 0 set mo 2 29 set mo 1 31 amp set mo 3 31 amp set mo 4 30 amp set mo 5 31 set mo 6 30 amp set mo 7 31 amp set mo 8 31 amp set mo 9 30 set mo 10 31 amp set mo 11 30 amp set mo 12 31 set  a past y  days 365  set  a monthdays days-  past y 365    past y 4  1   amp  amp set  a past y cur y-past y amp set months 0  setmonth set  a minusmonth  cur m-1 -months if  minusmonth  leq 0 set  a minusmonth  12 set  a checkdays  mo  minusmonth   if  monthdays  geq  checkdays  set  a months  1 amp set  a monthdays- checkdays amp goto  setmonth set  a past m cur m-months set  a lastmonth cur m-1 if  lastmonth  leq 0 set  a lastmonth  12 set  a lastmonth mo  lastmonth  set  a past d cur d-monthdays amp set adddays    if  past d  leq 0  set  a past m- 1 amp set adddays   if  past m  leq 0  set  a past m  12 amp set  a past y- 1  set mo 2 28 amp set  a leapyear past y 10 4 if  leapyear  -1  equ 0 set mo 2 29  adddays set  a past d  mo  past m  set d  past m - past d - past y  for  f  tokens      a IN   xcopy      d  d   L  I null   do  if exist     nxa  set  excludefiles  excludefiles      nxa    for  f  tokens      a IN   dir  b   do    echo   excludefiles   FINDSTR  C      a    gt nul    if exist     nxa  DEL  F  Q    a  gt nul 2 gt  amp 1    NOTE  The code above takes into account leap years  as well as the exact number of days in each month  The only maximum is the total number of days there have been since 0 0 0  after that it returns negative years    NOTE  The math only goes one way  it cannot correctly get future dates from negative input  it will try  but will likely go past the last day of the month

IMO  JavaScript is gradually becoming a universal scripting standard  it is probably available in more products than any other scripting language  in Windows  it is available using the Windows Scripting Host   I have to clean out old files in lots of folders  so here is a JavaScript function to do that      run from an administrator command prompt  or from task scheduler with full rights    wscript jscript js    debug with    wscript  d  x jscript js  var fs   WScript CreateObject  Scripting FileSystemObject     clearFolder  C   temp  cleanup     function clearFolder folderPath           calculate date 3 days ago     var dateNow   new Date        var dateTest   new Date        dateTest setDate dateNow getDate   - 3        var folder   fs GetFolder folderPath       var files   folder Files       for  var it   new Enumerator files    it atEnd    it moveNext                   var file   it item             if  file DateLastModified  lt  dateTest                        var filename   file name              var ext   filename split      pop   toLowerCase                 if  ext     exe   amp  amp  ext     dll                                 file Delete true                                      var subfolders   new Enumerator folder SubFolders       for     subfolders atEnd    subfolders moveNext                  clearFolder subfolders item   Path             For each folder to clear  just add another call to the clearFolder   function  This particular code also preserves exe and dll files  and cleans up subfolders as well

Run the following commands   ROBOCOPY C  source C  destination  mov  minage 7 del C  destination  q   Move all the files  using  mov  which moves files and then deletes them as opposed to  move which moves whole filetrees which are then deleted  via robocopy to another location  and then execute a delete command on that path and you re all good     Also if you have a directory with lots of data in it you can use  mir switch

Gosh  a lot of answers already  A simple and convenient route I found was to execute ROBOCOPY EXE twice in sequential order from a single Windows command line instruction using the  amp  parameter   ROBOCOPY EXE SOURCE-DIR TARGET-DIR      MOV  MINAGE 30  amp  ROBOCOPY EXE SOURCE-DIR TARGET-DIR      MOV  MINAGE 30  PURGE   In this example it works by picking all files     that are older than 30 days old and moving them to the target folder  The second command does the same again with the addition of the PURGE command which means remove files in the target folder that don   t exist in the source folder  So essentially  the first command MOVES files and the second DELETES because they no longer exist in the source folder when the second command is invoked   Consult ROBOCOPY s documentation and use the  L switch when testing

Expanding on aku s answer  I see a lot of people asking about UNC paths  Simply mapping the unc path to a drive letter will make forfiles happy  Mapping and unmapping of drives can be done programmatically in a batch file  for example   net use Z   delete net use Z    unc path to my folder forfiles  p Z   s  m   gz  D -7  C  cmd  c del  path    This will delete all files with a  gz extension that are older than 7 days  If you want to make sure Z  isn t mapped to anything else before using it you could do something simple as  net use Z    unc path to my folder if  errorlevel  equ 0       forfiles  p Z   s  m   gz  D -7  C  cmd  c del  path    else       echo  Z  is already in use  please use another drive letter
