Batch file to rename a file to ddmmyy.txt

[nortyrich]

I am trying to write a batch file that will be scheduled to run once daily in order to rename a constantly growing datafile to ddmmyy.txt. I would like to use the DOS system DATE variable but need to know how to manipulate the string from dd/mm/yyyy format to ddmmyy. Is there an easy way of doing this or can somebody point me in the right direction?

I've managed to solve this now, just by using the same syntax as described in the SET command help as follows

@Echo off
SET dd=%date:~0,2%
SET mm=%date:~3,2%
SET yy=%date:~8,2%
SET ndate=%dd%%mm%%yy%

REN c:\datafile.txt "l"%ndate%".txt
