Try this:

% Specify the folder where the files live.
myFolder = 'D:\My Pictures\Misc'; % Wherever...
% Check to make sure that folder actually exists.  Warn user if it doesn't.
if ~isdir(myFolder)
  errorMessage = sprintf('Error: The following folder does not exist:\n%s', myFolder);
  uiwait(warndlg(errorMessage));
  return;
end
% Get a list of all files in the folder with the desired file name pattern.
filePattern = fullfile(myFolder, '*.PNG'); % Change to whatever pattern you need.
theFiles = dir(filePattern);
for k = 1 : length(theFiles)
  baseFileName = theFiles(k).name;
  fullFileName = fullfile(myFolder, baseFileName);
  fprintf(1, 'Now reading %s\n', fullFileName);
  % Now do whatever you want with this file name,
  % such as reading it in as an image array with imread()
  imageArray = imread(fullFileName);
  imshow(imageArray);  % Display image.
  drawnow; % Force display to update immediately.
  % Create a folder with the base file name
  [~, baseFileNameNoExt, ~] = fileparts(baseFileName);
  outputFolder = fullfile(myFolder, baseFileNameNoExt);
  if ~exist(outputFolder, 'dir')
    mkdir(outputFolder);
    fprintf('Created folder : %s\n', outputFolder);
  end
  % Prepare output filename
  outputFileName = fullfile(outputFolder, baseFileName);
  % Copy file to that folder
  copyfile(fullFileName, outputFileName);
  fprintf('    Copied %s to the folder called %s.\n', baseFileName, outputFolder);
end

I am not understanding how to put this code in above code to detect face from each images and crop the face and then save the cropped face as image in created folders. Instead of copy file i want to save cropped face in the folder of image. This code is for face detection and cropping face...

     FaceDetect = vision.CascadeObjectDetector;
        FaceDetect.MergeThreshold = 7 ;
        BB = step(FaceDetect,img); figure(2),imshow(img);
        for i = 1:size(BB,1)
           rectangle('Position',BB(i,:),'LineWidth',3,'LineStyle','- ','EdgeColor','r');
        end
    figure
      for i = 1:size(BB,1)
        J= imcrop(img,BB(i,:));
        subplot(6,6,i);
        imshow(J);
      end
      end

After imshow you need to call imwrite():

drawnow;
imshow(J, filename);
