Closing a Project
Closing a Project closes all open files in the Project. If any file contains unsaved changes, before closing the file, a window opens, asking whether you want to save these changes. In this case, you must click Yes or No to continue.
To close a Project, do one of the following:
Click the X in the upper right corner of the window.
Select File > Close Project.
In the Project Navigator, click the < Click to close Project > command that is shown in the file open state. For more information, see Project Navigator.
