PPTX
PPTX (noun) means the standard file format for slide presentations used by Microsoft PowerPoint since 2007, based on the Office Open XML standard.

Frequently Asked Questions
What is the difference between PPT and PPTX?
PPT is the older binary PowerPoint format; PPTX, from PowerPoint 2007 onward, stores the same presentation as a zipped set of XML files. PPTX files are usually smaller and easier for other software to read, and PowerPoint still opens both.
Should I send a PPTX or a PDF?
A PPTX stays editable and keeps animations, transitions and speaker notes, but it can look different on another machine if the fonts are missing. A PDF fixes the appearance exactly and opens anywhere, at the cost of losing animation and editability. Which suits depends on whether the recipient needs to change the slides.
What is the difference between PPTX and POTX?
A POTX is a PowerPoint template: it carries the layouts, theme colours and placeholder slides but is meant to be the starting point for new presentations. Opening a POTX creates a fresh PPTX based on it rather than editing the template itself.
