Have you ever created a new presentation in PowerPoint and then closed it without saving it for even once? This scenario seems to be little strange and impossible since even if you accidentally close your presentation, PowerPoint prompts you whether you want to save your presentation. Yet, you can be in a similar scenario if you lose all your file changes to a system or PowerPoint crash. Fortunately, there are chances that your unsaved presentation is safe in some state!

Alternatively, even if you don’t see any files being offered for recovery, you can set the process in action manually.
