MATLAB: How to loop through all files in subfolders in a main folder

foldersubfolder

Hello,
I have a main folder and several subfolders in it. Each subfolder has several files within them. I want to create a loop in such a manner that the code would open a subfolder, do what I want it to do and then move to the next one.
Thanks in advance

D = 'full path to the main folder';
S = dir(fullfile(D,'*'));
N = setdiff({S([S.isdir]).name},{'.','..'}); % list of subfolders of D.
for ii = 1:numel(N)
    T = dir(fullfile(D,N{ii},'*')); % improve by specifying the file extension.
    C = {T(~[T.isdir]).name}; % files in subfolder.
    for jj = 1:numel(C)
        F = fullfile(D,N{ii},C{jj})
        % do whatever with file F.
    end
end
