What is the final step in closing the package for CD dialog?

The final step in closing the package for the CD dialog is to click the close button. This action signifies that you have completed the process of packaging your PowerPoint presentation for distribution on a CD. Clicking the close button effectively exits the dialog window after the necessary actions have been taken, ensuring that all changes are saved and that the user is returned to the main interface of PowerPoint without any interruptions.

It is important to note that other options, like clicking the cancel button or export button, would lead to different outcomes: the cancel button would discard any actions taken and close the dialog without saving, while the export button would initiate a different workflow related to exporting files rather than finalizing the closing of the package process. The okay button typically signifies confirmation, but in the context of the CD dialog, it is not the step that concludes the process. Thus, closing the package properly involves using the close button to exit the dialog as the final step.
