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.
How do I set Windows Explorer to show file extensions?
To set Windows Explorer to show file names with file extensions, do the following:
In Windows Explorer, click Folder and Search Options. In Windows 7, this is under Organize. In Windows Vista and Windows XP, on the Tools menu, click Folder Options.
On the View tab, under Files and Folders, clear the check box for Hide extensions for known file types.
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.
Right-click the file and click Rename.
Change the file extension to .zip.
Press ENTER. The file type icon changes to a zipped folder. Double-click the folder to open.
The zipped file contains several folders , many of which contain information such as XML code or properties . Objects such as videos, sound files or documents are found in the ppt folder.
To restore the original presentation Repeat this procedure, changing the file extension from .zip to .pptx.
