What “reviewed” means on this page
  • Format fit: whether the “what is this file?” description plausibly matches common real-world use of the extension, including category, typical MIME types, and aliases.
  • Opening paths: whether Windows / macOS / Linux steps read plausibly for current OS dialogs and default apps. Not every step was tested on every OS version.
  • Security framing: whether risk notes match the extension class (for example executables vs plain data) and whether affiliate wording does not contradict the security section.
  • Sources and further reading: external links should point to vendors, standards bodies, or other primary references where possible; not every detail is individually sourced.
  • Limits: this is clarity and safety-messaging QA, not a guarantee that every statement is exhaustive or that every binary you download is harmless. Pages without “Reviewed by” have not been through this editorial pass yet.

What is a .PPT file?

Background

Over time, the format has evolved, but it remains popular due to its wide compatibility and feature set. While newer versions of PowerPoint use the .PPTX format, .PPT files are still supported by most presentation software. Users can include text, images, charts, and multimedia in their presentations, making it a versatile tool for communication.
