Extract files or objects from a PowerPoint 2010 file

If you want to separately use files or objects from a Microsoft PowerPoint 2010 presentation, such as videos, photos, sounds or documents, you can extract them by converting the presentation to a “zipped” file folder.
Before you do this procedure, make sure Windows Explorer is set so that it shows file names with file extensions.

 TIP    You can later change the file extension back and restore the presentation, but we recommend that you copy the presentation first and extract the objects that you want from the copy. This ensures your original presentation is preserved.
To open a presentation as a folder, use Windows Explorer to navigate to the folder containing the presentation that you want, and then do the following:
Click the presentation that you want, then right-click it and then click Rename.
Change the file extension (.pptx) to .zip. Press ENTER to set the name, then click Yes in the Rename dialog box.
Double-click the zipped file to open an Explorer window for the content files.
