\chapter{Save and Open Project}\label{sec:USSavingOpeningProject}


\section{Saving a project}
The project can be saved at a location defined by the user.

\section{Opening a project}
The user must be able to open an existing project. 
When calculations were made, also the calculation results must be shown.
The results will not be shown when made by a previous version of \ProgramName, because the results can be outdated. \newline
\Note{In version 25.1 it is not possible to open previous \ProgramName (*.damx) projects because there were too much changes. 
A workaround for this is to recreate the project again with the original source data 
(see \autoref{sec:USCreateDesignProject} or \autoref{sec:USCreateCalamityProject}).}
