What is POT?
POT is the legacy template format for Microsoft PowerPoint, used in versions prior to Office 2007. It stores slide layouts, themes, fonts, colors and placeholder design that serve as a reusable starting point for new presentations.
POT files use PowerPoint's older binary file structure rather than XML. When opened, a POT template provides the design framework for a new presentation. In Office 2007 it was superseded by the XML-based POTX (and macro-enabled POTM) formats.
How a POT Template Works
POT stores its data in Microsoft's compound binary (OLE structured storage) container, the same underlying structure as the PPT presentation format, holding slide masters, color schemes, fonts, and placeholder design rather than finished slide content.[2] Opening a POT applies its design to a new presentation, providing a consistent visual framework.[3]
History and Succession
POT belongs to the binary PowerPoint family used from the 1990s through Office 2003, before Microsoft moved to Office Open XML with the 2007 release.[3] It was superseded by the XML-based POTX template and the macro-enabled POTM, which replaced the single binary template with separate macro-free and macro-bearing formats.[1]
Compatibility and Limitations
Modern PowerPoint can still open POT files for backward compatibility, though the binary format is more opaque and harder to parse than the later ZIP-and-XML templates.[1] Because the compound binary structure could embed automation and OLE objects, legacy templates warrant the same caution as other binary Office files.[2]
MKV Technical Specifications
POT vs Other Presentation Formats
| Feature | POT | POTX | PPTX |
|---|---|---|---|
| Type | Legacy PowerPoint template[1] | OOXML template | OOXML presentation |
| Structure | Binary (97-2003)[2] | Zipped XML | Zipped XML |
| Editable | Yes | Yes | Yes |
| Open/proprietary | Proprietary[3] | Open OOXML | Open OOXML |
| Device/app support | Legacy PowerPoint | Modern PowerPoint | Near-universal |
| Best for | Old template reuse | New templates | General slides |
POT preserves compatibility with older PowerPoint, whereas POTX and PPTX use the modern XML format with smaller files and broader support.
Advantages & Disadvantages
Advantages
A POT template captures themes, layouts and placeholders so new presentations start with a consistent design.
As an old PowerPoint format, POT opens in essentially all versions of PowerPoint and many third-party viewers.
The binary structure stores template design efficiently for the era it was created in.
Disadvantages
POT is a legacy binary format that has been replaced by POTX, and modern features may not be fully supported.
Unlike the XML-based POTX, the binary format is not human-readable and is harder to process with standard tools.
Common Use Cases
POT is mainly encountered with older presentations and template libraries.
Legacy template libraries | FileFormer
Older organizations may still hold POT design templates created in PowerPoint 97-2003.
Branded presentation themes | FileFormer
Companies historically distributed POT files to enforce a consistent slide design.
Conversion to modern formats | FileFormer
POT files are often converted to POTX to keep older templates usable in current PowerPoint.

What is the difference between POT and POTX?
POT is the legacy binary PowerPoint template used before Office 2007, while POTX is the newer Office Open XML template format. POTX uses ZIP-and-XML packaging and is the current standard.
Can modern PowerPoint open POT files?
Yes. Current versions of PowerPoint can open legacy POT templates and let you save them in the modern POTX format for continued use with newer features.
Is a POT file a presentation?
No. A POT file is a template, not a finished presentation. It provides the design, layouts and themes used to create new PowerPoint files, which are saved as PPT or PPTX.
How do I convert POT to POTX?
Open the POT file in PowerPoint and use Save As, choosing PowerPoint Template (.potx). This stores the design in the modern Office Open XML template format.
