Hi @David Duque,

To enable users to select a specific folder for saving notes from a text area in MATLAB App Designer, the “uigetdir” function can be utilized. This function prompts the user to choose a directory from their desired file storage location. For detailed information, refer to the following official documentation:

https://www.mathworks.com/help/matlab/ref/uigetdir.html

The existing implementation can be enhanced by replacing it with the following code:

% Get the value entered in textArea 
value = app.TextArea_.Value; 

% Prompt the user to select a folder 
folder = uigetdir(pwd, 'Select Folder to Save Notes'); 
if folder == 0 
    disp('User canceled folder selection.'); 
    return; 
end 

% Full path to the new file 
fileName = ‘DataReport.txt’; 
fullFileName = fullfile(folder, fileName); 

% Save the text to the file 
writecell(value, fullFileName, 'QuoteStrings', false); 

This approach ensures that the user is prompted to select a folder before proceeding. Upon successful selection, a new file named “DataReport.txt” is created in the chosen directory, and the contents of the text area are written to it.
