In a world where businesses share data with each other every day, PPTX - PowerPoint Open XML Presentation is proving to be the best program for creating slide show presentations. PPTX, as the program is often called, works with Microsoft PowerPoint. PowerPoint Open XML files, however, are stored in a different format than traditional PowerPoint Files. PPTX files have a .xml extension, in contrast to the .ppt extension.
With PPTX, files are stored individually within a compressed zip file. An entire slideshow can be transferred, because the zip format compresses all the data. If only a single slide is needed, though, then the presentation can be unzipped and the single file for that slide can be sent. PowerPoint’s traditional format does not have this capability. With .ppt files, the entire slideshow must be sent. The different file format also makes extracting an image or text box from a slide simpler than it used to be.
PPTX is compatible on both Windows and Mac OS X. On Windows, it is supported by PowerPoint 2007 and newer versions. On Apples, it is supported y PowerPoint 2008 or later. In either case, PPTX can open PowerPoint files from before 2007.
