What is a .VSSM file?
A .VSSM file is a type of file that works with a program called Visio. Visio is a tool that people use to create diagrams for business purposes. These diagrams can be anything from flowcharts to organizational charts. The .VSSM file holds a bunch of different shapes that you can use to make your diagrams look exactly how you want them to. It's similar to another file type called .VSSX, but with a special feature: it can run macros.
Macros are like little programs that can do tasks for you automatically. So, if you have a .VSSM file, it means you can use these macros to help set up your shapes in the diagram more easily or do special formatting things without having to do everything by hand. This can save a lot of time and make your diagrams look more professional with less effort.
To open a .VSSM file, you need to have Microsoft Visio 2021. This is the program that understands how to work with these files and lets you use all the shapes and macros inside them to create your diagrams.
Sometimes, businesses or organizations prefer to use .VSSM files instead of .VSSX files because they want to make sure that the people making diagrams can do so more efficiently, thanks to the macros. So, if you're given a .VSSM file, it's because it has some handy automation features built into it to help you out.
