Hi Paul,
MATLAB projects (.prj files) are designed to help manage and share work by automatically setting up environment to its saved state when the project was last closed. This includes path settings, which should restore while opening a project.
I understand that you are experiencing an issue where MATLAB is not able to restore the project's path settings when opening a project from a .prj file. There might be a few reasons and solutions to explore:
- Check Project Setup: MATLAB projects can include startup and shutdown scripts (startup.m and shutdown.m). Verify that these scripts are correctly configured and do not inadvertently alter the path in ways that override the project's settings.
- Use Project Shortcuts: If specific actions, such as adding paths or setting up the environment, need to be performed when project opens, consider using “Project Shortcuts”. Create shortcuts for scripts that set up the environment, ensuring that any necessary paths are added when the project starts. Please refer to the following link-https://www.mathworks.com/help/simulink/ug/what-can-i-do-with-project-shortcuts.html?searchHighlight=Projects%20shortcuts&s_tid=srchtitle_support_results_1_Projects%20shortcuts
- Automate with Startup Scripts: If project's automatic path restoration feature does not meet the needs, create a startup.m script in project's root directory. This script runs when MATLAB starts and can use it to programmatically to add necessary paths using the “addpath” function. For example:
if isfile(fullfile(pwd, 'myProject.prj'))
addpath(genpath(pwd)); % Adds the current directory and subdirectories to the path
% Add any other necessary setup commands here
end
MATLAB projects should automatically manage and restore path settings as part of their design. If this is not happening, checking project configurations, and using startup scripts to manually manage paths when the project opens are all viable strategies.
Please refer to the following documentation link-

- Startup- https://www.mathworks.com/help/matlab/ref/startup.html?searchHighlight=startup.m&s_tid=srchtitle_support_results_2_startup.m
Hope it helps!
