@Medwaymike Welcome to the Serif Affinity forums   We do not plan to support the legacy file formats (.PPP, .DPP or .SPP) in the Affinity range, sorry. The latest versions of those programs continue to work and we would suggest you continue using them for projects you have already invested a lot of time in, and use the Affinity range for your new projects going forward, or import PDF where you want new functionality provided by the Affinity software.
