MATLAB: How to delete selected images from a folder

acess foldercell arraydeleteselected images

Hi everyone, I have a group of images and I want to delete some of them, selected by their contents.
They are all named with a progressive name (Img000001, ImgA000002 and so on…) and I have collected the numbers of the ones I want to keep in the vector 'ok' with this code:
% Image acquisition and crop
tiffFiles = dir('*.tif'); 
numfiles = length(tiffFiles);
cell = cell(1, numfiles);
count=0;
ok = zeros();
for k = 1:numfiles 
cell{k} = imread(tiffFiles(k).name); 
cell_adj{k} = imadjust (cell{k});
cell_crop{k} = imcrop (cell_adj{k}, [0,30,1616,300]);
cell_sub{k} = cell_crop{k}-cell_crop{1};
cell_2bw{k} = imbinarize(cell_sub{k}, 0.25);
  if cell_2bw{k} == zeros()
     cell_2bw{k} = [];
  else
    ok(count) = k-1; 
    count = count + 1;
  end
end
Now I don't know how to access the folder and delete the selected files. Thank you for your help!

You code fails: You start with
count = 0;
ok = zeros();
and later on:
     ok(count) = k-1; 
     count = count + 1;
Now ok(0) is accessed in the first iteration and this is an error. Incread count before using it as index.
What about this:
if cell_2bw{k} == 0
   delete(tiffFiles(k).name);
end
