.bat - delete files by creation date

hello....

i need a batch file (.bat) or help on one...
Basically i need something that can delete the file on basis of the date it was created.

I am gonna use it for deleting my logfiles that are a week old.

Any suggestion???

thanks

Hi
Until somebody comes up with the answer I create a hold folder then use scheduler to run a batch file that clears out last weeks and moves this weeks in.
