I have a folder where every day backup files are copied from a system.
I need to create a batchfile and put in the windows schedule that deletes the file older than seven DAYS.
How do I do it ?
I found this online. I hope it helps...

Code: [Select]:: --------DELOLD.BAT----------
echo off
SET OLDERTHAN=%1
IF NOT DEFINED OLDERTHAN GOTO SYNTAX

for /f "tokens=2" %%i in ('date /t') do set thedate=%%i

set mm=%thedate:~0,2%
set dd=%thedate:~3,2%
set yyyy=%thedate:~6,4%

set /A dd=%dd% - %OLDERTHAN%
set /A mm=%mm% + 0

if /I %dd% GTR 0 goto DONE
set /A mm=%mm% - 1
if /I %mm% GTR 0 goto ADJUSTDAY
set /A mm=12
set /A yyyy=%yyyy% - 1

:SET28
set /A dd=28 + %dd%
goto DONE

:SET29
set /A dd=29 + %dd%

:DONE
if /i %dd% LSS 10 set dd=0%dd%
if /I %mm% LSS 10 set mm=0%mm%
for %%i in (*.*) do (
set FileName=%%i
call :PROCESSFILE %%~ti
)

set mm=
set yyyy=
set dd=
set thedate=
goto EXIT

:SYNTAX
ECHO.

Thanks,

This file delete the latest file - today's file . Is because of the date format ?
My date format is mm-dd-yyyy.

This file should delete the files older than 7 days. So there should not be any parameter passing .
Please let me know where to edit the batch file to give a FIXED value of 7 ?you should at least understand what the batch script is doing before using. Here's a MUCH shorter vbscript. don't have to WORRY about date settings.
Code: [Select]Set objFS = CreateObject("Scripting.FileSystemObject")
strFolder = "c:\test"
Set objFolder = objFS.GetFolder(strFolder)
For Each strFile In objFolder.Files
If DateDiff("d",strFile.DateLastModified,Now) > 30 Then
strFileName = strFile.Name
WScript.Echo strFileName
objFS.DeleteFile(strFileName)
End If
Next

on command prompt
Code: [Select]c:\test> cscript /nologo myscript.vbs

want SOMETHING even shorter? you can download GNU find (see my sig under findutils)
Code: [Select]C:\test>find c:\test -type f -mtime +30 -delete
