create_missing = false;
parts = {'C:\', 'Users', 'user', 'Documents', 'mu'};
if ~exist(parts{1}, 'dir')
    error('You do not have a C: drive. Giving up.');
end
failed = false;
for K = 2 : length(parts)
    thispath = fullfile(parts{1:K});
    if exist(thispath, 'dir')
        fprintf('Okay we already have directory %s\n', thispath);
    elseif create_missing
        try
            mkdir(thispath);
            fprintf('Was able to create missing directory %s\n', thispath);
        catch
            fprintf('Failed trying to create missing directory %s', thispath);
            oldpath = fullfile(parts{1:K-1});
            p = fileattrib(oldpath);
            fprintf('Attributes of parent directory %s are:\n', oldpath);
            disp(p);
            failed = true;
            break
        end
    else
      fprintf('Directory %s does not exist and you asked that missing directories not be created. Set the variable create_missing to true if you want the directory created\n', thispath);
      failed = true;
      break
    end
end
if failed
    fprintf('Some directory not created. Not ready to use\n');
else
