How to use waitbar while copying images from folders and subfolders

I have stored the images in a folder named 'dataset' , which contains subfolders as 'red' , 'brown' , 'black' , and each folder contains abt 50 images. I want to copy these images into a folder named 'testing data' , meanwhile , while copying the images I want to display a waitbar which shows the copying process , I did try out somethings but couldn't succeed .The code is as :

clear all
clc
M_dir = 'C:\Users\Dell\Documents\MATLAB\dataset\';% source directory
D_dir = 'C:\Users\Dell\Documents\MATLAB\testing_data\';
files = dir(M_dir);
dirFlags = [files.isdir];
subFolders = files(dirFlags); 

mkdir testing_data
           
for k = 1 :length(subFolders)
     if any(isletter(subFolders(k).name))
         c_dtry = strcat(M_dir,subFolders(k).name);
              fileList = getAllFiles(c_dtry);
                 h = waitbar(0,'Please wait...');
        for i=1:150
              for n1 = 1:length(fileList)
                
                  [pathstr,name,ext] = fileparts(fileList{n1})% file type 

                  Im = imread(fileList{n1});
                  f=str2num(name);
  
                  
                 if(f>=1 & f<=50)
                    baseFileName = strcat(name,ext);
                    imwrite(Im, fullfile(D_dir, baseFileName));
                 elseif(f>=59 & f<=83) 
                     baseFileName = strcat(name,ext);
                    
                    imwrite(Im, fullfile(D_dir, baseFileName));
                    
                  elseif(f>=109 & f<=133) 
                     baseFileName = strcat(name,ext);
                    imwrite(Im, fullfile(D_dir, baseFileName)); 

                 end
                 
              end
               waitbar(i/80,h)
        end

     end    
end

Basically ,I have tried in many places but could not find the answer, I would appreciate it if you could help me to solve this problem !!! Thank you :)

What I would do is first make a list of all sources and targets, and then do the actual copying in a loop like this

h_wait=waitbar(0,'copying...');
N=numel(sources);
for n=1:N
    copyfile(sources{n},destinations{n})
    waitbar(n/N,h_wait)
end

That should work

Thanlk you sir . Sir I did try to run the code , but it is giving me error for brackets , did do some changes , but its not working . Sir please help me to figure it out . Thank you sir:)

[Rik]

What code did you use to generate the sources cell array and the destinations cell array? And what specific error message are you getting?
