Rather than 'opening recipe files' you now 'search for recipes' using the Recipe Open dialog. When you save a recipe it must have a unique ID Number. The recipe report, for example, now displays both recipes with their calculated chemistries, pictures and notes. There are many other types of reports that generate similar kinds of detail. You can define your own set of typecodes and then assign them to recipes.
Recipes can have multiple typecodes.
