parse some folders in specific directory within particular names in matlab

I've written this code , My problems are: 1- When implement code its only views the value of x and writes only the first image from folder test1 to folder temp or to folder discard . 2- How can I write All images in folder test1 to folder temp or discard . 3- Then if I have folders from test 1 to test n how can I repeat this process for all folders with particular name test(i) in a specific directory D to check every image in test folders and complete remaining procedure? Thanks...

    % srcFolders = dir('D:\test*');
for folder = 1:length(srcFolders)
    path = strcat('D:\',srcFolder(folder).name);
    sear = strcat(path, '\*.bmp');
    srcFiles = dir(sear);
    for i = 1 : length(srcFiles)
        filename = strcat(path,'\',srcFiles(i).name);
        Image1= imread(filename);
        Image2 = imread('D:\2','jpeg'); % Image 2
        x=diff(Image1 - Image2); %display the result to console
        if (x >= 0.05)
            name1 = strcat('D:\temp2\',srcFiles(i).name);
            imwrite(Image1, name1); 
            disp('Value 111111111111.')
            disp(x)
        else
            name2 = strcat('D:\temp3\',srcFiles(i).name);
            imwrite(Image1, name2); 
            disp('Value 222222222222.')
            disp(x)
            end
       end 
  end
