You may organize the objects presented in the Repository Tree for the Repository as a while.
Repository organization is very important as you may schedule, assign responsibilities, and perform actions (right-click) by folder.
Steps
1. Sign in as a user with at least the Metadata Editor capability object role assignment to the configuration you wish to organize.
2. Go to MANAGE > Repository.
3. Right-click on the Repository or any folder and select Create > Folder to create folders.
Thus, folders may contain folders.
4. Drag any object into a folder to organize.
Moving an object in the Repository Tree changes the unique path (ID) used to uniquely identify the object, e.g., in the REST API or in the URLs. In addition, all responsibility object role assignments are cleared and then re-computed based upon inheritance.
