projectdir = 'name of main directory goes here';
dinfo = dir(projectdir);
dinfo(~[dinfo.isdir]) = []; %remove non-folders
dinfo(ismember({}, {'.', '..'}) = []; %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] );
rename(old_file, new_file);
catch ME
fprintf('Failed to rename "%s" to "%s"\n', old_file, new_file );

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