Save files in different folder based on condition

Hello, I have several signals that are the output as text files (which contain different information after the signal processing which could be named as the matrix A for simplification) and they have different flags based on the results obtained after processing each individual data. As an example, let us say the following.

Processedfile1: flag 1=0, Flag2=0, Flag 3=0 (This does have any issue)

Processedfile2: flag 1=1, Flag2=0, Flag 3=0 (This have an issue in MATLAB coding and needs implementation)

Processedfile3: flag 1=1, Flag2=0, Flag 3=1 (This should be discarded)

.

.

.

Processed file n: flag 1=0, Flag2=0, Flag 3=0 (This does now have any issue)

Therefore, based on the output of each signal, they should be saved as text files in a sulbfolder (where the functions and data are located) or different folder outside the current one (Disk drive D inside a folder) like this:

Inside the folder or subfolder "Unflagged_folder": Processedfile1.txt, Processedfilen.txt.

Inside the folder or subfolder "Flagged_folder": Processedfile3.txt

Inside the folder or subfolder "Implement_code_for this case": Processedfile2.txt

Thank your for your help

% define your sub/folder locations, using absolute or relative paths:
ok_folder = 'Unflagged_folder';
implement_folder = 'Implement_code_for this case';
discard_folder = 'Flagged_folder';

% loop over files:
for ii = 1:n
    
    % ...
    % generate matrix A and flag1, flag2, flag3 for file ii
    % ...
    
    % select the correct folder, based on the values of flag1, flag2, flag3:
    % (the actual logic you use may be different than this)
    if flag3
        folder = discard_folder;
    elseif flag1
        folder = implement_folder;
    else
        folder = ok_folder;
    end
    
    % write matrix A to file:
    filename = fullfile(folder,sprintf('Processedfile%d.txt',ii));
    writematrix(A,filename);
    
end
