why not moving??

I had a series of files named S0009, S0010, etc and turned them dicom images with dicomwrite, renaming them to test1.dcm, test2,dcm etc.. Now I want to transfer all test1,2,3.dcm files to another subfolder. I use this, although I get no error, still they are not moving.

destinationFolder = 'C:\Echo Images\Stelios\FDB.dcm\TeSt';
if ~exist(destinationFolder,'dir')
    mkdir(destinationFolder);
end
dir 'C:\Echo Images\Stelios\FDB.dcm'
listing = dir('.dcm');
[m n z] =  size(listing);
for indx=3:m
  listing(indx).name
  A = dicomread(strcat( 'C:\Echo Images\Stelios\FDB.dcm\' , listing(indx).name)); 
  imshow(A);
  I3 = imcrop(A, [200.5 59.75 591 480]);
  %A =  imresize(A, [360, 280]);
  W = dicomwrite(I3, strcat('C:\Echo Images\Stelios\FDB.dcm\test',  int2str(indx-2) , '.dcm'));
  fullfileName = fullfile(destinationFolder,W)
  dicomwrite(W,fullfileName)
end

The return value from dicomwrite is a strut of status information. You try to use the strut to build a file name and then do a second dicomwrite of just the status information which is not valid data to write.

What is the intent of having the two dicomwrite?
