Redux itself does not care about how your application's folders and files are structured. However, co-locating logic for a given feature in one place typically makes it easier to maintain that code.Because of this, we recommend that most applications should structure files using a "feature folder" approach (all files for a feature in the same folder) or the "ducks" pattern (all Redux logic for a feature in a single file), rather than splitting logic across separate folders by "type" of code (reducers, actions, etc).
