1. Get the Files in the directory... ([~,ListofImages]=dos('dir   /b /s te_*.jpg');)
2. Get the Number from it..(1, 2, etc) (RegExFileName = '[0-9]+_new'; [~,StartIdx]=regexpi(FileName, RegExFileName , 'match');)
3. Format New Name, (NewFileName=['tour',num2str(index),'_pictures'])
4 do a movefile to rename.. movefile(SourceFileName, NewFileName);

MATLAB: How to rename multiple files located in subfolders within a main folder

How about the following?

D = struct2table(dir('./**/*'));
D = D(~D.isdir,:);
for kk = 1:height(D)
  [~,folderName] = fileparts(D.folder{kk});
  newFileName = ['P',folderName,'_',D.name{kk}];
  movefile(fullfile(D.folder{kk},D.name{kk}),fullfile(D.folder{kk},newFileName));
end

MATLAB: Problem using move file

what you're missing is

path = 'C:\temps (IT do not delete)\matlabAnswers\dirtest\';
dirData = dir(strcat(path,'*.wav'));                          %# Get the selected file data
fileNames = {dirData.name};                                   %# Create a cell array of file names
for iFile = 1:numel(fileNames)                                %# Loop over the file names

newName = strcat('hole',fileNames(iFile),sprintf('%d',iFile));     %# Make the new name

movefile(fileNames{iFile},cell2mat(newName));                         %# Rename the file

end

i used wav files as i had a directory full of junk wav files. just change to png.. so the initial problems are:

in the move file the newName was a cell. that is why it asked for a string.
in the sprintf you were printing the number as a string. so it made it an empty space after the new name.

I'm not exactly sure if you want to put the numbering after the .wav#. perhaps you wanted holeFilename#.wav

then you substitute the for loop with something like this

for iFile = 1:numel(fileNames)                                %# Loop over the file names
newName = strcat('hole',fileNames{iFile}(1:end-4),sprintf('%d',iFile),'.wav');     %# Make the new name
movefile(fileNames{iFile},newName);                         %# Rename the file
end
