There are three ways to clone (copy) a project:
If you clone a project with the same name and in the same location as an existing folder, the contents (subfolders and resources) of the project are merged with the contents of the target folder.
In either case, the original project remains unchanged.
For instructions, see Cloning a Project and Demoting the Clone to a Folder.
Use a unique name to create the clone as a new project, or use the name of an existing project to merge the clone with that project.
Use a unique name to create a new folder, or use the name of an existing folder to merge the clone with the existing folder (in the location you will select in the next step).
