Usually our Keynote presentations contain a lot of media files and objects such as videos, photos, images, sounds or documents – pdfs- or other embedded objects. You can easily extract these files or objects from a Keynote presentation by converting the presentation to a “zipped” file folder.
Note: You can use this method to extract files from PowerPoint files too.
Here is how:
1-Locate the Keynote presentation (or PowerPoint)
2-Make a copy of the presentation file. Simply right click on the file and select duplicate.
3-Now you will have the duplicate. In our example here, it is the appletoolbox copy file. Now select this new file by clicking on it and press enter to change the file extension. Not change the file extension to .zip by typing .zip after the file name. So in our example, this is appletoolbox copy.zip, as shown below:
4-Now click Use .zip when you see the following message:
5-Now, unzip this new zip file by double-clicking it. This will create a new folder, which includes the content files.
6-This will include several files. Videos, sound files or documents are found in the Data folder. Now you can copy any files, objects you would like.
