Saving files in a standalone .mlapp app

I am making a mlapp file in app designer, that I want to use as a standlone app. I have to save some .mat files in this app, and I noticed that when I try to run an app with double click on .mlapp file, I always get this error:
Error using save
Unable to write file BR_constraction_par.mat: permission denied
Then with pwd command I found out that app runs from C:\Windows\System32 and that is why I can't save my file. How can I cd to the folder where .mlapp file is located, if I don't know the path?
.

Hello, you can get the full path of the .mlapp file using:
appPath = mfilename('fullpath');
appDir = fileparts(appPath);
appPath will return the full path including the .mlapp file name, while fileparts will then return the folder location of the .mlapp file.
Hope this helps
