What is VSSM file format?

VSSM (Visio SmartShape Master) is a file format used in Microsoft Visio, a popular diagramming and vector graphics application. The VSSM format is used to save SmartShape masters, which are the basic building blocks used to create custom shapes in Visio. SmartShapes are pre-built shapes that contain special behavior, such as the ability to automatically resize and adjust their appearance based on the content they contain. SmartShapes can also contain special functionality, such as data graphics, links to external data sources, and macros.

The VSSM file format stores the shape data, as well as any associated metadata and behaviors. This allows users to create complex shapes with a wide range of custom properties and behaviors that can be easily reused and shared across multiple Visio documents. VSSM files are also used to create stencils, which are collections of shapes that can be used to quickly create diagrams with a consistent look and feel.

VSSM files can be edited and created using Visio’s Shape Designer tool, which allows users to customize the shape’s appearance and behavior. The resulting VSSM file can then be saved and shared with others, allowing them to use the custom shape in their own Visio diagrams. The VSSM format is an essential component of Visio’s customization capabilities, and is widely used by professionals in fields such as engineering, architecture, and software design.

What is POTM file format?

A POTM file refers to a macro-enabled presentation template created using Microsoft PowerPoint, a software program used for creating slide show presentations. It includes default images, slide templates, macros, and formatting. POTM files are commonly used by PowerPoint users to create multiple .PPTM files with consistent designs and macro settings.

POTM files offer additional functionality compared to typical presentation files, as they support macros. Macros are script-like functions that automate repetitive tasks within PowerPoint. Users can record macros that can be replayed to perform specific actions and assign them to buttons or keystrokes for convenient execution. To record a macro, users can select View → Macros in PowerPoint.

For general presentation creation, users can save their files as .PPTX or .POTX files. However, if they want to create a template that incorporates macros, they can save their presentation as a POTM file.

It’s worth noting that POTM files were introduced by Microsoft when they released Microsoft Office 2007.

To open a POTM file, Microsoft PowerPoint (2007 or later) is the recommended application for full support of presentation formatting and embedded macros on both Windows and macOS. Alternative applications like Apache OpenOffice Impress, Kingsoft Presentation, and Apple Keynote can also open POTM files, but some formatting and macros may not be fully preserved. For Mac users looking to view a POTM file without editing, Apple Preview (bundled with macOS) or Google Drive, a free cloud storage service, can be used.

Online platforms like Google Slides allow users to upload POTM files for viewing, editing, and conversion. However, it’s important to note that Google Slides does not support macros.

To convert a POTM file, various presentation applications including Microsoft PowerPoint, Apple Keynote, and OpenOffice Impress offer conversion capabilities. In Microsoft PowerPoint for Windows and Mac, users can select File → Save As and choose from formats such as .PPTX, .PPT, .PDF, .ODP, .XPS, .MP4, .WMV, .JPEG, and .PNG to convert the POTM file to their desired format.
