A disk file that is located inside the frame of a data processing system is provided with an electromagnetic shield that is made of a conductive cloth-like material. The material has an inner layer of woven glass fibers, a plastic coating on one side, and an aluminum foil that is bonded to the other side by heat and pressure. The file has an irregular shape but is approximately a rectangular box. A wooden pattern is formed in the shape of the file, and the cloth is formed over the top and sides of the pattern by conventional sewing techniques. The bottom of the pattern corresponds to a surface of the file that is mounted against a metal support plate that provides electromagnetic shielding in this direction. The hem of the shield contains an elastic that maintains electrical contact with conductive components of the file.
