PPTX files are presentations created with Microsoft
PowerPoint versions 2007 and above. PowerPoint was released by Microsoft in
1990 and is currently the most popular application for developing presentations
and for putting together commercial and non-commercial slideshows.
PowerPoint presentations are made of individual pages
also known as “slides” which can contain text, videos, pictures, music, sound
effects, charts and other graphic objects. All elements can be arranged freely
within each page.
The PPTX Open XML file format was developed by
Microsoft to replace the older PPT format. PPTX files save all data in a
compressed ZIP archive which contains three folders with RELS, XML and media
files. All files can be extracted individually by changing the extension from
PPTX to ZIP and opening the document with any decompression utility.
Unlike PowerPoint slideshows, finished PowerPoint presentations
are fully editable. They can be opened and edited with PowerPoint or simply
showcased with PowerPoint Viewer.
