Batch script to delete file older than 1 day.

D means: Run date am passing through command prompt.

How to subtract one day in D.

I want to delete one day old file,the file name starting with olddayfile_20140323.txt in same code.

Am using below code for Deleting D (D:current day file) files.

@echo on

rem %1 %2 %3 - YYYY MM DD

set folder1="C:\FX\in"

set folder2="C:\FX\out"

set D=%1%2%3%

cd /d %folder2%

del test1_%1%2%3*

del test2_%1%2%3*

del test3_%1%2%3*

Please note below script is working,but it's working only modified date files.

forfiles.exe /p C:\FX\out /s /m olddayfile_* /d -1 /c "cmd /c del @file"

Please suggest me am new for Batch script.

  • Many questions on this question. See [Batch file to delete files older than N days](http://stackoverflow.com/questions/51054/batch-file-to-delete-files-older-than-n-days?rq=1) – Laura Mar 24 '14 at 08:58
  • Is filename pattern the only criteria to determine file age? And, should the code delete only one day old files or anything older than that? – MC ND Mar 24 '14 at 09:03
  • possible duplicate of [Batch script to delete files older than X days (based on creation date, not modified date)](http://stackoverflow.com/questions/17785216/batch-script-to-delete-files-older-than-x-days-based-on-creation-date-not-modi) – Endoro Mar 24 '14 at 09:14
  • Do your files have YYYYMMDD in the filename, and you want to delete files one day old when using that date? – foxidrive Mar 24 '14 at 10:29
  • Are you assuming D as Current date or it as your manual input and whether file name is in the format of YYYYMMDD – SAT Mar 24 '14 at 11:11
  • @SAT D means: Run date am passing through command prompt.yes file format is in YYMMDD . ex: olddayfile_20140323.txt – user3243364 Mar 24 '14 at 11:17

Try below code for delete the file with name of one day less than current date (format YYYYMMDD)

 @echo off
 setlocal

 Call :GetDateTime Year Month Day
 set A=%Year%%Month%%Day%

 Call :SubtractDate %Year% %Month% %Day% -1 Ret

 set b=%Ret%
 @echo ###start Deleting
 :: variables
 Set source=G:\


 echo ### Deleting up old backup...
 DEL /Q /S "%source%\%B%*.*"

 if %yy% LSS 100 set /a yy+=2000 &rem Adds 2000 to two digit years
 set /a JD=dd-32075+1461*(yy+4800+(mm-14)/12)/4+367*(mm-2-(mm-14)/12*12)/12-3*((yy+4900+(mm-14)/12)/100)/4
 if %a:~0,1% equ + (set /a JD=%JD%+%a:~1%) else set /a JD=%JD%-%a:~1%

 set /a L= L-1461*I/4+31, J= 80*L/2447,  K= L-2447*J/80,      L= J/11
 set /a J= J+2-12*L,      I= 100*(N-49)+I+L
 set /a YYYY= I, MM=100+J, DD=100+K
