Merge multiple PowerPoint files into 1.

Caller: "How do I combine all of ppt files into one big one"? I replied: " Yes, of course this can be done" and then I said, to myself- where do they (Microsoft) have it hidden?  It took a few minutes, the answer came to me, but what a great opportunity to add this content to my blog for future reference. 


1.  With PowerPoint opened, from the Home tab, click on New Slide and select Reuse Slides...

2.  From the Reuse Slides pane, click on Browse to locate pptx file and select Browse File...

3.  Select the file and click on Open.  The slides appear within the Reuse Slides pane.  At the bottom check Keep source formatting, to retain slide formatting.

3.  Right-click on Slide 1 and select Insert Slide or Insert All Slides.

4. From the View tab, within the Presentation Views group, click on Slide Sorter to help move/arrange slides.  Save the file.
