Extract Embedded File From Powerpoint Presentation

i attended a sharepoint seminar few week ago. the Presentation is awesome and view informative. The speaker show us some great demo. he told us that those source code had been embedded in the powerpoint file.

I download the PPTX file, and try to extrac the embedded file via the Powerpoint software interface. But there is no such option or functio to allow me to get the task done.

i google the internet and finally get the solution from Microsoft Office Web site.

the main point of the solution is to rename the PPTX file to a Zip file and use a zip utility software to open the zip file, the you will be able to find embedded file in the embeddings folder.

please read the following link for complete detail instruction.
