A PPTX file, like the old ppt files, can contain not only formatted text, lists, pictures, videos but also music and Excel spreadsheets, which are divided into boards or slides. In addition, many elements can be animated or fade in and out, as well as with different effects. PPTX files can not contain macros, files with macros automatically get the extension pptm. The files are editable and will not start automatically.

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

Office Open XML is an open standard developed by Microsoft for office applications, which is intended to ensure the file exchange between different office suites.
