In this paper, we study groupoid actions acting on arithmetic functions. In particular, we are interested in the cases where groupoids are generated by directed graphs. By fixing a prime p and a graph G, we establish a noncommutative free probabilistic structure embedded in the algebra of all arithmetic functions. We act the additive group (ℝ, +), the flow, on the free probability space dependent both on p and on G, and construct uncountable families of free probability spaces determined by the flow. We study fundamental properties of such a family.
