Can someone explain why entropy is an extensive property as opposed to a state property?

Entropy is an extensive property because it depends on the amount of substance available. However, it is also a state property because it doesn't matter the pathway it takes to get there, but the final minus initial states.

is it not a state function? if i recall correctly, entropy is in fact a state function because it does not depend on the path followed by the system--just the final and initial state. however, the entropy does depend on the size or amount of moles. entropy=q/T, and q itself is extensive

Entropy is a state function since they describe quantitatively an equilibrium state of a thermodynamic system.
