Disabling Magento Extension Manually

Some time we need to disable extension manually, its easy to do as as every magento extension create its XML file in 'app\etc\modules' folder like our extension name is 'AdvLay_Nav' so it will create file named AdvLay_Nav.xml when u open it you will see code like this

<?xml version="1.0"?>
<config>
    <modules>
        <AdvLay_Nav>
            <active>true</active>
            <codePool>local</codePool>
            <self_name>Advance Layed Navigation</self_name>
            <priority>10120</priority>
        </AdvLay_Nav>
    </modules>
</config>

go to <active> tag edit it to 'false' and clear your magento cache in var folder and you are done.
