A stack of coated conductors is a perspective configuration for various applications of high temperature superconductors. We solve magnetization problems for a stack of flat films of an arbitrary shape using a fast Fourier transform-based numerical method. A properly rescaled solution for a stack of only several films is employed to obtain an accurate approximation to the solution for stacks containing a large number of densely packed films. For an infinite stack the problem simplifies and becomes similar to that for a single film.
