projectdir = 'name of main directory goes here';

num_subdir = length(dinfo);

  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

Use the following function GetAllSubDirAndFiles(main_folder) where main_folder is the path to the folder containing all the subfolders containing the files you want to rename. The output contains all the folders and files. Then you can rename the files

% Example :

[subfolders, files] = GetAllSubDirAndFiles(main_folder);

Then files{1} is a cell containing all files that are in the subfoler subfolders{1} and so on for files{2}, etc.

Here are the two functions you need

function [sub,fls] = GetAllSubDirAndFiles(main_folder)
   [sub, fls] = subfolder(main_folder,'','');
function [sub,fls] = subfolder(main_folder,sub,fls)
tmp = dir(main_folder);
tmp = tmp(~ismember({tmp.name},{'.' '..'}));
for i = {tmp([tmp.isdir]).name}
   sub{end+1} = [main_folder '\' i{:}];
   if nargin==2
      sub = subfolder(sub{end},sub);
   else
      tmp = dir(sub{end});
      fls{end+1} = {tmp(~[tmp.isdir]).name};
      [sub, fls] = subfolder(sub{end},sub,fls);
   end% if
end% for

You should add the renaming part. So the total code is :

[subfolders, files] = GetAllSubDirAndFiles(main_folder);
for k = 1:length(subfolders)
   for i = files{k}
       old_filepath = fullfile(subfolders{k}, '/', strjoin(i));
       ind = max(strfind(subfolders{k}, '\'));
       new_filepath = fullfile(subfolders{k}, '\', [subfolders{k}(ind+1:end), '_', strjoin(i)])
       movefile(old_filepath, new_filepath);
   end
end
function [sub,fls] = GetAllSubDirAndFiles(main_folder)
   [sub, fls] = subfolder(main_folder,'','');
function [sub,fls] = subfolder(main_folder,sub,fls)
tmp = dir(main_folder);
tmp = tmp(~ismember({tmp.name},{'.' '..'}));
for i = {tmp([tmp.isdir]).name}
   sub{end+1} = [main_folder '\' i{:}];
   if nargin==2
      sub = subfolder(sub{end},sub);
   else
      tmp = dir(sub{end});
      fls{end+1} = {tmp(~[tmp.isdir]).name};
      [sub, fls] = subfolder(sub{end},sub,fls);
   end
end
