How do you confirm the compression of media in PowerPoint?

To confirm the compression of media in PowerPoint, closing the Compress Media dialog allows you to see the final results of any compression that has been applied. When using the Compress Media feature, PowerPoint displays a window that provides the specific details about the compression process, including the new file sizes of the media elements and the overall effect on the presentation. Once you close this dialog, you can typically return to your presentation and check the reduced sizes directly in the Media section or through the Info view, ensuring that the compression has taken place as intended.

In this scenario, while checking the summary in the Info view can provide some additional context or information about the overall presentation size, it may not specifically highlight the compression results as effectively as closing the Compress Media dialog would. Returning to the previous screen and inspecting file sizes may also help in confirming that compression occurred, but they are not direct methods for confirming the completion of the compression process itself. Therefore, closing the Compress Media dialog is the most straightforward way to finalize and confirm media compression in your PowerPoint presentation.
