What tool allows a user to organize features into "folders" in the part navigator?

The correct choice is that it’s called "Feature Folders." This tool allows users to categorize and organize features in the part navigator, enhancing the ability to manage complex models by grouping related features together. By using feature folders, designers can keep their workspaces tidy, making it easier to navigate through various features of a design, especially when dealing with larger assemblies or intricate parts.

Feature folders help maintain clarity in a project by allowing users to collapse or expand sections of the feature tree, thus streamlining the design process and improving workflow efficiency. While feature groups do exist and refer to a similar concept of combining features, they do not specifically designate the organizational aspect in the part navigator as feature folders do.
