How can i delete a certain audio file?

[inix92]

I recently rooted my s4 and im trying to find the audio file that makes the beep when the phone is connected to the charger. When i go to media/audio all i get is a notification folder and nothing else. How can i find that audio file to delete it?

Thank you

Welcome to the forums.
I know this may be more of a hassle than deleting the audio file, but you could turn your phone to silent or even turn it off before plugging it in.
