for i = 1:size(TrainFiles,1)
if not(strcmp(TrainFiles(i).name,'.')|strcmp(TrainFiles(i).name,'..')|strcmp(TrainFiles(i).name,'Thumbs.db'))
Train_Number = Train_Number + 1; % Number of all images in the training database
name{Train_Number}=TrainFiles(i).name;
end

It's checking to make sure that the file is not the current folder (dot) or a link to the parent folder (dot dot).

I would use
allFileNames = fullfile(yourImageFolder, {fileStructure.name});
