Regarding Account terminating from WHM panel

I have recently bought a Reseller hosting service and i want to know that if I terminate an account (which is an active website) via whm panel then does the files of that website (into its public_html) also gets deleted ?

I have posted it so to get confirmed that the files (inside public_html) does not occupy the space in my hosting server. Or do I need to first delete those files and terminate the account ?

Thank you (in Advanced) for your valuable solution.
