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

Walter Roberson, i have just modified the following :
rename (old_file, new_file);
with
movefile(old_file, new_file);
and its working fine .. but the problem its keep the renaming files in parent directory instead of it source directory..
in other words.. all text files are renamed successfully but its moved to parent folders not in folder1, folder2 ..etc.?
new_file = fullfile( projectdir, this_subdir, [this_subdir '-' this_file] );
thank you very much ... very great code..

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

Is there any renaming process in your code ? can you please suggest me when i have to put rename code if possible..
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
Thank you very much... its working fine..
