I've created the folder to write images on it by the code

 outputFolder = fullfile(cd, 'folder_name');
  if ~exist(outputFolder, 'dir')
    mkdir(outputFolder);

and I'm in need to overwrite the same folder for writing another set of images. Is there any way to delete all the existing images in the folder for writing new images???

My folder should be reused only the content should by deleted...

It's easier and safer (IMHO) to delete the directory with everything in it and then re-create it if you want to protect yourself from cruft or some error condition that pops up later because some other file is left over from a previous run ... or the wildcard match missed a .PNG file (or pNG, pNG, PNg, .png~ etc) ... or some other weirdess happens.
