The paper presents three criteria which aid in solving the problem of allocating copies of a file in a computer network. The criteria simplify the problem because (a) they can be applied a priori to determine that certain sites will (or will not) be included in the optimal allocation, and (b) they can become an integral part and accelerate a search procedure for finding an optimal allocation.
