I am a newbie. And I am using 4.1.11. Where is the file "auth.php" located? I looked all over, I only see auth.tpl, is that the same? Second, where so I upload the file change_ppp.php? same location at auth.tpl?

And I can't found
{* $Id: products.tpl,v 1.72.2.3 2006/11/27 11:40:25 max Exp $ *}
{if $active_modules.Feature_Comparison ne '' && $products && $printable ne 'Y' && $products_has_fclasses}
{include file="modules/Feature_Comparison/compare_selected_button.tpl"}
{include file="modules/Feature_Comparison/products_check_js.tpl"}

{/if}
skin1/customer/main/products.tpl

Am i missing anything? or Am I looking at different verison?

I am not a programmer.
Please help, Thanks!
