To All,

My problem is, I use a batch file to copy all contents of the Z drive and put them in C:\htmlbackup\%date%
IE
C:\htmlbackup\2004-04-01
C:\htmlbackup\2004-04-02
C:\htmlbackup\2004-04-03
C:\htmlbackup\2004-04-04
And so on.

So I want to create a batch file that will delete all folders older than 7 days of the current date.
IE
Current date = 2004-04-10
I want to delete all folders before 2004-04-03

I will use Scheduled Tasks to run the batch file every 7 days.  I am using Windows Server 2003.

Thanks

Try this:

@echo off
setlocal

set yyyy=

set $tok=1-3
for /f "tokens=1 delims=.:/-, " %%u in ('date /t') do set $d1=%%u
if "%$d1:~0,1%" GTR "9" set $tok=2-4
for /f "tokens=%$tok% delims=.:/-, " %%u in ('date /t') do (
 for /f "skip=1 tokens=2-4 delims=/-,()." %%x in ('echo.^|date') do (
    set %%x=%%u
    set %%y=%%v
    set %%z=%%w
    set $d1=
    set $tok=))

if "%yyyy%"=="" set yyyy=%yy%
if /I %yyyy% LSS 100 set /A yyyy=2000 + 1%yyyy% - 100

REM Substract your 7 days here
set /A dd=1%dd% - 100 - 7
set /A mm=1%mm% - 100 + 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

:ADJUSTDAY

if %mm%==1 goto SET31
if %mm%==2 goto LEAPCHK
if %mm%==3 goto SET31
if %mm%==4 goto SET30
if %mm%==5 goto SET31
if %mm%==6 goto SET30
if %mm%==7 goto SET31
if %mm%==8 goto SET31
if %mm%==9 goto SET30
if %mm%==10 goto SET31
if %mm%==11 goto SET30
if %mm%==12 goto SET31

echo ERROR: unexpected month:
echo dd=%dd% mm=%mm%, yyyy=%yyyy%
goto :EOF

:SET31

set /A dd=31 + %dd%

goto DONE

:SET30

set /A dd=30 + %dd%

goto DONE

:LEAPCHK

set /A tt=%yyyy% %% 4

if not %tt%==0 goto SET28

set /A tt=%yyyy% %% 100

if not %tt%==0 goto SET29

set /A tt=%yyyy% %% 400

if %tt%==0 goto SET29

: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%

set _CutOff=%yyyy%-%mm%-%dd%

set mm=
set yyyy=
set dd=
set tt=

REM ** Here is where you specify what you want to scan

for /F "delims=" %%i in ('dir /b /ad c:\htmlbackup') do if /I %%i LSS %_CutOff% echo rd "c:\htmlbackup\%%i" /s /q

set _CutOff=

Remove the echo statement to activate the rd command.

Good Luck,
Steve

If you don't mind installing the free and powerfull Perl from (for instance)
http://www.activestate.com/Products/ActivePerl/?_x=1

I made the script below
1. safe: it will first display the dirs it keeps or remove (not deleting anything), please test
2. safe: it tries to change dir to where your backups are or leave if it cannot
3. safe: it works only on directories with name like year-month-day
4. after testing it, when you are ok, just uncomment the line "# rmtree($_);" => "rmtree($_);" to do the actual deletion

run the script (make sure perl is reachable):  perl  delbkp.pl
(note that file path are / based, not \ :)

--------script please call it  'delbkp.pl'------------------
#!perl

$NUMBER_OF_DAYS = 7;

$home = "C:/htmlbackup";

use File::Path;
use Time::Local;

chdir ($home) or die "Cannot change dir to $home";

$now = time();

for (<[12][0-9][0-9][0-9]-[0-1][0-9]-[0-3][0-9]>)
{
  if ( -d $_ )
  {
    split(/-/,$_);
    $before = timelocal(0,0,0,$_[2],$_[1]-1,$_[0]-1900);
    $delete = (($now - $before)/86400 > $NUMBER_OF_DAYS);
    print "$_ ", ($delete ? "remove":"keep"), "\n";
    #
    # uncomment (remove the #) the next line when you are ok!

    # rmtree($_) if ($delete);
  }
}
