Ordering products by date creation as "DESC" by default

Hi everybody,

By default I set in Virtuemart "Ordering by Creation date", but it display product from older to newer.
Do you know how to reverse the return by default ? (so DESC and not ASC)?
I had just found the way that change the order was by editing the following file:
administrator/components/com_virtuemart/models/product.php
Change:
$filter_order_Dir = strtoupper (JRequest::getWord ('order', 'ASC'));
to
$filter_order_Dir = strtoupper (JRequest::getWord ('order', 'DSC'));
But there isn't the file: administrator/components/com_virtuemart/models/product.php in VM 2.0.10.

Plz help me! Thanks a lot.

After changed setting "Ordering by Creation date" did you clear your joomla cache ?

Regards

Thanks. I done it.
