% Directory
directory = 'C:\Datasets\nyu\train\';
img_dir = fullfile(directory, 'image_02');
depth_dir = fullfile(directory, 'depth');
image_rgb_info  = dir( fullfile(img_dir, '*.jpg'));
image_rgb_filenames = fullfile(img_dir, {image_rgb_info.name} );
image_depth_info = dir( fullfile(depth_dir, '*.png'));
image_depth_filenames = fullfile(depth_dir, {image_depth_info.name} );

MATLAB: How to select images from nested folder

Something like this should work. You will possibly need to add code to appropriately sort your list of images. I've marked where you would do it.

imageFolder = uigetdir('', 'Select Image Folder');
destinationFolder = uigetdir(imageFolder, 'Select Destination Folder');
contents = dir(imageFolder);
fileList = contents(~[contents.isdir]);
% Sort list as needed here
filesToMove = fileList(1:10:end);
fromPaths = fullfile(imageFolder,{filesToMove.name});
toPaths = fullfile(destinationFolder,{filesToMove.name});
for fileIdx = 1:numel(fromPaths)
    copyfile(fromPaths{fileIdx}, toPaths{fileIdx})
end

Also I'm note sure the specific relevance of folders AAA and A. If AAA, A, and B are all known folders and you want to create C based on them, you could replace the uigetdir code with something like

imageFolder = fullfile(AAA,A,B);
destinationFolder = fullfile(AAA,A,C);
if ~exist(destinationFolder, 'dir')
    mkdir(festinationFolder);    
end
