More info

A PPSX file can contain, in addition to formatted text, lists, pictures, videos, as well as the old pps files, music and Excel spreadsheets, which are subdivided into display boards or slides. In addition, many elements can be animated or fade in and out, as well as with different effects. Ppsx files can not contain macros. The files contain a complete slideshow and are no longer editable. They are started automatically, assuming compatible software.

PPSX is an XML based file format (Office Open XML) that is unreadable with earlier versions of PowerPoint. For the Office versions 2000, 2003 and XP, however, this functionality can be used with the help of the Microsoft Office Compatibility Pack, whereby the result of an imported PPSX file does not always have to be 100% identical to the original.

A PPSX file consists of several XML files, which are automatically summarized as archives when saved using the ZIP algorithm. This saves space compared to the old format. Other benefits include better data integrity and easier data recovery in case of data loss.

OpenOffice.Org and LibreOffice do not directly support the files, but can open them if the option 'Microsoft PowerPoint 2007 XML' is selected.
