projectdir = 'name of main directory goes here';
dinfo = dir(projectdir);
dinfo(~[dinfo.isdir]) = [];   %remove non-folders
dinfo(ismember({dinfo.name}, {'.', '..'}) = [];   %remove . and .. directories
num_subdir = length(dinfo);
for S = 1 : num_subdir
  this_subdir = dinfo(S).name;
    subdinfo = dir( fullfile(projectdir, this_subdir, '*.txt') );
    num_subfile = length(subdinfo);
    for F = 1 : num_subfile
      this_file = subdinfo(F).name;
      old_file = fullfile( projectdir, this_subdir, this_file );
      new_file = fullfile( projectdir, [this_subdir '-' this_file] );
      try
        rename(old_file, new_file);
      catch ME
        fprintf('Failed to rename "%s" to "%s"\n', old_file, new_file );
      end
    end
end
