A .vpsm file is a Rapid Insight Scoring Model. This is a model that has been memorized within Predict and has been saved outside of the software so that it can be shown to others or scored against an original dataset.
A .vpa is a Rapid Insight Analysis. A saved analysis is made up of imported data and one or several memorized models. A .vpa file can also be re-opened in Predict to continue working with the same data and models in the Analysis at a later time without having to import data or build models over again.
To save as a .vpsm select Memorize Model, then click the model name and select Save. For more information on how to save an analysis, click here.
