You can link Test Plans to any number of Test Plan Folders. This will help you manage your Test Plans. As you increase the number of test plans in your project, the organization of your content becomes increasingly important. Grouping test plans into folders and sub-folders helps tremendously.
You can use folders to group test plans for specific functions, requirements, or different test types, such as performance tests, integration tests, or system-level tests.
