sourcefolder = 'C:\DT3\Pictures';
destfolder = 'C:\DT3\Pictures\SmallPicture';
if ~isfolder(destfolder); mkdir(destfolder); end
dinfo = dir(sourcefolder);
dinfo([dinfo.isdir]) = []; %remove subfolders and . and ..
filenames = fullfile({dinfo.folder}, {dinfo,name});
nfiles = length(filenames);
for K = 1 : nfiles
thisfile = filenames{K};
info = imfinfo(thisfile);
if ~isempty(info) && isfield(info, 'Width') && isfield(info,'Height') && info.Width <= 512 && info.Height <= 512
copyfile(thisfile, destfolder);
catch ME
%not an image, or headers not readable or copyfile failed

use dir to loop through all files in the folder you mentioned.
use imfinfo to check the width and height of each image file in that folder.
use copyfile to copy the relevant files and mkdir if needed to create the SmallPicture directory

Sir Roberson, your answer was posted about 2 hours ago, same as mine. Obviously, I wrote this answer while you wrote yours, hence i missed it. Honestly, this happens quite often and I fail to see why you reproach or tease me on that matter.
