What is a PPTX file?

A .pptx file is a ZIP archive with one XML part per slide, plus slide layouts, a theme and any embedded media. Images and video are stored as ordinary files inside the package, so presentations are often large.

Speaker notes, slide masters and layouts are separate parts linked by relationship files, which makes the format modular but intricate to generate by hand.

How to recognise a PPTX file

The first bytes of every file. The same signature as any ZIP archive, because the file is a ZIP package.

The MIME type is application/vnd.openxmlformats-officedocument.presentationml.presentation. The file extension is .pptx.
Is a sample PPTX file the same as a dummy or example PPTX file?
Yes. Sample, test, dummy and example PPTX files are different names for the same thing: a PPTX file with known contents that stands in for a real one. Any file on this page will do wherever a tutorial or a test plan asks for a dummy PPTX file.
