Is it possible that I set a parameter one day before today?

So I read out the system time:

 set ARCHIV=%DATE:~0,2%%DATE:~2,2%%DATE:~4,6% 

And now the output is 12.06.2014 (DD.MM.YYYY)

And I want that the output is 11.06.2014

I really don't know if it's possible to subtract the output date with one day. I had found only commands to subtract it with another date.

Regards

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 %b%
 @echo ###start Coping
 :: variables
 Set source=F:\
 Set destination=F:\
 set backupcmd=xcopy /s /c /d /e /h /i /r /y
 echo %drive%
 echo %destination%
 echo ### Backing up My folder...
 %backupcmd% "%source%" "%destination%\%b%"
