Where are the save save as open and close commands located in the backstage view?

In the Backstage view of Microsoft Office applications, the "Save," "Save As," and "Open" commands are found on the left-hand sidebar. The "Save" command is usually at the top, while "Open" is typically listed just below it. The "Save As" option can be accessed by clicking on "Save a Copy" or directly through the "Save As" option if available. The Backstage view can be accessed by clicking the "File" tab in the ribbon.
