What is a POT file?

The POT extension denotes a legacy Microsoft PowerPoint Template file used in PowerPoint versions 97 through 2003. It is structured around the Compound File Binary Format (CFBF), acting as a container for OLE objects, streams, and storages. This binary format stores master slides, layout definitions, and styles intended for replication across multiple .PPT presentation files, predating the XML-based architecture introduced in Office 2007.

How to open a POT file

As a legacy format, POT files are natively supported by all modern versions of Microsoft PowerPoint on Windows and macOS, often running in 'Compatibility Mode'. For users without a Microsoft 365 subscription, free alternatives such as LibreOffice Impress, Google Slides (via upload), and Corel Presentations can parse and edit the binary structure effectively.

What is a PPSX file?

The PPSX (PowerPoint Open XML Slide Show) format is a presentation file introduced by Microsoft with Office 2007, adhering to the Office Open XML (OOXML) standard (ISO/IEC 29500). It acts as a read-only slideshow version of the PPTX format, launching directly into presentation view rather than the editing interface. Structurally, it is a ZIP archive containing XML documents that define slide layouts, themes, and content, but it explicitly excludes the vbaProject.bin part found in macro-enabled variants, ensuring it cannot execute code.

How to open a PPSX file

Native support for PPSX is built into Microsoft PowerPoint 2007 and newer versions on Windows and macOS. To edit a PPSX file rather than view it, users must open PowerPoint first and select the file via the 'Open' menu. Alternative software includes LibreOffice Impress, Google Slides, and Apple Keynote, all of which can parse the OOXML structure, though some transition animations may not render identically to the Microsoft engine.
