copying multiple images from one folder to other folder

Dear Matlab Users ,

I have 10 folders contain images in the following folder ( " D:\ second_folders ") , inside this folder there are 10 folders names ( folder1 , folder2 ..... , folder10 ) , i need to read each image in each folder and copy the image to another main folder ("D:\ master_folder" ) if its satisfy conditions and put it that copied image in same folder name that it comes from .. for example if image1 was read from folder1 in D:\ second_ folder and satisfy conditions then copied to folder1 in D:\ master_folder and so on for others images in folders ,,,

conditions are : 
image type must be .jpg or .png type , 
image size must be >=50 KB ,

thanks ..

What have you tried so far and which problems occurred?

What does this mean: "image dimension must be appropriate like Width=600 and hight=100 not accepted" ??

clear all
clc

M_dir = 'D:\ second_folders'% source directory
D_dir = 'D:\ master_folder'
files = dir(M_dir);% main directory
dirFlags = [files.isdir];
subFolders = files(dirFlags);%list of folders

for k = 1 :length(subFolders)
    if any(isletter(subFolders(k).name))
        c_dtry = strcat(M_dir,subFolders(k).name)
             fileList = getAllFiles(c_dtry)%list of files in subfolder
             for n1 = 1:length(fileList)
                 [pathstr,name,ext] = fileparts(fileList{n1})% file type 
                 s = dir(fileList{n1});
                 S = s.bytes/1000;%file size
                 Im = imread(fileList{n1});
                 [h,w,d] = size(Im);%height width and dimension
                 if ((strcmp(ext,'.jpg')|strcmp(ext,'.png'))&S>=50&(write image dimension condition))%  here you need to modify
                    baseFileName = strcat(name,ext); 
                    fullFileName = fullfile(D_dir, baseFileName); % No need to worry about slashes now!
                    imwrite(Im, fullFileName);

                   end
               end

      end
  end

line no??

[ahmed obaid]

there are no line following : all screen shoot info

M_dir =

D:\ second_folders

D_dir =

D:\ master_folder

Index exceeds matrix dimensions.

work space screen

files         <0x1 struct>
k      1       min 1   max 1 
subFolders    <0x0 struct>

[ahmed obaid]

ok now there are no errors but does not work ..

[Stalin Samuel]

verify directory paths in your pc with 'M_dir' and 'D_dir'

[ahmed obaid]

sir i have verify directory path , add your function to matlab path , but dirFlags [] is still empty i think its not able to read subdirectory folders , and K= [] and subfolders is struct 0x0 struct ??
