Hi, I understand that e-Junkie's PDF stamping doesn't allow customers to download updated products with their original download links (even if reactivated). My question is this: My original product was a 80mb pdf. It was updated to a smaller 30mb pdf later. Presumably, customers will only be able to download the old 80mb file. Does that mean that this larger file is still being stored in my disk space? How does this work?
