folder='D:\answers\'
for k=1:1
file1=sprintf('%d.png ',k)
file2=sprintf('00%d.png',k)
dos_com=['!rename ', folder file1 file2]
eval(dos_com)
end
Edited code (Simon's suggestions)
folder='D:\answers\' % e.g
for k=1:4
file1=[folder sprintf('%d.png ',k)]
file2=[folder sprintf('00%d.png',k)]
movefile(file1 ,file2]
end

Have you moved the existence test to before you imwrite() ? Are you doing something meaningful when you find that the file exists?
And are you truly wanting to output exactly the same output file for BlobsNo's worth of files ? Notice that once you have converted the image to grayscale when k=1, and resized to 40 x 40, that subImage will remain grayscale and 40 x 40 for all the rest of the values of k.

Also,
sprintf('%03d.png', FileNumber)
to get the leading zeros

As will the traditional C-like way:
baseFileName = sprintf('%3.3d.png', FileNumber);
