Hi, I am quite keen to shift from Aperture to Affinity as I am not sure about how Apple is going to support Aperture in the future. I would like to know how easy it is to export a complete library from Aperture into Affinity, and how the library architecture and the filing structure of all the assets works within Affinity ? I have around 75,000 pictures most of them retouched split into 500 projects. Thanks a lot in advance.
