How does ACF Engine store custom post types, taxonomies and other objects?

ACF Engine takes the definition of your post types, taxonomies and other object (such as options pages, forms) and stores these in JSON. The JSON output folder is usually located at /wp-content/uploads/acfengine/. This directory has subdirectories for each object type, for instance you’ll find your post types at /wp-content/uploads/acfengine/post-types/.
