When creating a new project, you can use the default locations and names that Maya generates by default, or you can specify custom ones. You can also create new file rules to specify custom data locations for custom files. See Create custom data locations.
Maya populates the Project Window with default project locations and names.
This location is known as the project root directory. You can use this location for primary and secondary project locations and any other locations you add to your project.
Otherwise, the Primary Project Locations are added to the specified projects root Location.
Otherwise, the Secondary Project Locations are added to the specified projects root Location.
After you click Accept, Maya creates the project directories and sub-directories if they don't already exist.
Change how project location names are displayed
You can choose whether the Project Window displays your project location names as regular case text, or as file rule names, meaning in MEL nomenclature, by toggling between View in Nice Names and View in File Rules. For example, the nice name Source Images displays as sourceImages for its file rule name. By default, the Project Window displays projects locations as nice names (View in Nice Names).

The Project Window updates the display of your project locations.
