Find Unused Active Extensions help

[ron_rogers]

Hi All,

I'm taking over an unmanaged Magento 1.9 system with many Active Extensions.   

I believe many of the Active Extensions are unused.  

Short of turning them off and seeing what breaks, is there a way to determine if an Active extension is in use?  ie grep for an interface implementation, a registry? 

Thank you

@ron_rogers There is no way or interface where you can check whether any extension is in use or not instead you can do one thing, just check the extension functionality or see its system.xml file from where you can get its admin settings and then check whether you are using that particular extension or not.

Hope it helps!

Thanks
