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.
To start a new project
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.
This creates the project directories and sub-directories if they don't already exist.
