Sometimes you want to add slides from a Powerpoint presentation into your new one. Slide presentations need to be changed, updated, reformatted and just used for other purposes. Slide presentations are a bank of resources to be utilised. To add slides form one presentation to the other is the same on Windows and Mac but Windows will bring the slides to be selected up on the right. The images I am using are for the Mac because that is what we use at school.
1. Open the presentation
2. Click on New Slide top left in toolbar.
3. Select insert slides from other presentation.

4. Browse and choose the presentation you want to use. Click to open
5. Select slide(s) you want to insert
6. Click insert and continue with steps 4-6 until you have selected all the slides you wish.
Don’t forget to save it as your new presentation!
Cathy, great. How do you control formatting?
What is it you want to format? The slides will copy go into the presentation as you set them up but will adopt the new template if you have one.
I agree thoughsSometimes, I wish to keep the old format
Know what you mean. You would have to change that manually although some of mine import with the original template which is a bit odd and some take on the new template. Luckily I usually need them to change to the new template. It keeps the slide as you set it up but changes to the new colours/template format. At the moment it is pretty handy for me.
