Where to change Magento default tabs on products? -

i struggling problem hope can helpful with.

i need change default product tabs on product page, can't change in backend, set different attributes.

i have narrowed down catalog.xml file, don't know exact code controlling tabs.

i tried alter code bit, no effect. magento installation slow, driving me mad...

any ideas?

thanks in advance...

i suggest override core files in local module rather changing core file directly. here example how override mage_adminhtml_catalog_product_edit_tabs.php
create module example mynamespace_modulename inside app/code/local/

to register module create app/etc/modules/mynamespace_modulename.xml

<?xml version="1.0"?> <config>   <modules>    <mynamespace_modulename>      <codepool>local</codepool>      <active>true</active>    </mynamespace_modulename>   </modules> </config> 

mynamespace/modulename/etc/config.xml

<?xml version="1.0" encoding="utf-8"?> <config>     <modules>         <mynamespace_modulename>             <version>0.1.0</version>         </mynamespace_modulename>     </modules>     <global>         <blocks>             <adminhtml>                 <rewrite>                 <cataolg_product_edit_tabs>mynamespace_modulename_block_adminhtml_catalog_product_edit_tabs</cataolg_product_edit_tabs>                 </rewrite>             </adminhtml>         </blocks>     </global> </config>

        }         return parent::_preparelayout();     } } 

you can add new tabs inside _preparelayout() function. in same manner can override other files , can change whatever want change.
proper reflection of changes, make sure have clean cache.
