Microsoft PowerPoint utilizes various file extensions to differentiate between different types of saved presentations.
The primary file format for presentations is .pptx, which allows users to open and edit the slides.
The .PPSX Extension:
A presentation saved with the .ppsx extension is specifically designated as a PowerPoint Show.
The key characteristic of a .ppsx file is that it is programmed to automatically launch directly into Slide Show view when opened.
This means that the user bypasses the standard editing interface and immediately begins viewing the presentation as the audience would see it.
This format is ideal for quickly presenting a finalized slideshow without the risk of accidental edits.
