What is a .afpp file?

An .afpp file is a project file created by Apple's Aperture, a professional photo editing and management application. It doesn't contain the actual image data itself but rather stores all the adjustments, metadata, and organization settings applied to your photos within the Aperture library. Think of it as a blueprint for how your images are presented and managed. This allows for non-destructive editing, meaning your original image files remain untouched while Aperture applies edits virtually through the project file.
