Choose New File or New Folder from the File menu.
Type the name into the New File or New Folder field.
Click OK or press Return.
To close the New File or New Folder dialog box without creating a new file or folder, click Cancel or press Esc.
There are two other ways to create objects:
Copy an existing object, then rename the copy (see To Copy a File or Folder (Mouse)).
Create a new file within an application. For example, Text Editor creates a new file when you save a new document.
