PowerPoint 2007 does not have the Slide Finder feature. However, what it does have is something called Reuse Slides. To access this feature, click New Slide on the Home tab of the ribbon. Click Reuse Slides at the bottom of the New Slide window. Select Open a PowerPoint File and find the previous PowerPoint presentation with the slide or slides you want to copy. Right click a slide you want to copy in the Reuse Slides task pane and select Insert Slide.
