The "X" in the "PPTX" file extension stands for XML, or rather Open XML, the standard which Office 2008 for Mac (and also Office 2007 for Windows) now uses. It's not compatible with earlier versions of Office. As I understand it, the advantages are supposed to be smaller file sizes and more reliable storage of data.You can still save your files in the old PPT format if you like. The only catch is that PowerPoint 2004 and earlier may not be able to use some of the features you might have used in PowerPoint 2008 file. If you're not going to be sharing files with anyone, it's probably best just to stick with the PPTX format. But if you find that the PPTX format isn't your cup of tea then - Go to PowerPoint - Preferences - Save and change the default file format for saving PowerPoint files.

PPTX or PowerPoint Open XML file is a advanced version of PPT file. The file has xml in it. One can store individual files within a compressed zip file. An entire slideshow can be transferred, because the zip format compresses all the data. PPTX is compatible on both Windows and Mac OS X on windows it is supported by PowerPoint 2007 and further and on Apples it is supported by PowerPoint 2008 or later.
