How to get a msgbox with several lines of texts showing different variables?

Ive been working on a code and at the end I want a message box to pop up telling the user how many files were processed and how much time it took, ideally in the same message box. I want them on different lines but in the same box. Below is the code I wrote but I cant figure out how to make it work, ive tried several different formats. Thanks for any help in advance!

msg = sprintf(['Total files processed: %.0f', 1:numel(S); 'Elapsed Time: %.2f', toc]);
l = msgbox(msg);

msg = sprintf('Total files processed: %d\nElapsed Time: %.2f', numel(S), toc);
l = msgbox(msg);
