Will Affinity Publisher open/import InDesign documents? If Affinity Publisher imports IDML files it would be a help, but it would also mean that I need to open over 300 InDesign documents and then export them as IDML. When I upgrade my Mac OS, InDesign CS6 will no longer function, and I cannot afford the subscription cost to upgrade InDesign. I am looking at Affinity or Quark as alternatives. Markzware makes a converter from InDesign to Quark, but it costs $200, plus the competitive upgrade price to buy Quark for $450. If I can open InDesign documents directly in Affinity, it would be a major cost and time saver. Thank you for your assistance.
