You can save the current project using the menu item '''File → Save Project''', or by clicking the '''Save''' [[File:Save.png]] button of the System Toolbar. You can save the project under another name using the menu item '''Menu → File → Save Project As...'''. This opens up the standard Windows Save Dialog. The Windows Explorer shows the current location of the project folder. You can type in any name in the provided file path. Or you may change the folder and save the project in another location. "Save As" can be used to make additional copies of the same project under different names.
You can close a project at any time using the menu item '''File → Close Project'''. A message pops up that prompts if you wish to save the existing project. You can quit the [[EM.Cube]] application using the menu item '''File → Quit''' or using the keyboard shortcut "{{key|Ctrl+Q"}}. Note that when you close a project, you are still in the [[EM.Cube]] application. If you start a new project, you may still carry some of the program settings from the previous project. Quitting and exiting the application ensures that all the default settings would take effect the next time when you start a new project.
