[PS1.6] Order files by name in product page

[CriterioNet]

I need you to upload a file when you create a product, when displayed in the front end look in alphabetical order regardless of the order in which they went up (the default order is for the ID)

 

 

I was exploring the files but not well which make the change.

Files that I think you have to change are:

 

/public_html/controllers/admin/AdminAttachmentsController.php

/public_html/controllers/front/AttachmentController.php

 

or

/public_html/controllers/admin/AdminProductsController.php

/public_html/controllers/front/ProductController.php

 

Please any help or guidance to do this. Thanks
