 * If it references an existing entry and overwriting is not enabled (default case), an exception is raised. 
 * If overwriting is enabled the existing entry will be overwritten.

 * but the parent exists (in this case "/root/folder"), a new entry named by the last path component (in this case "leaf") is created.
