Hi,
The files in the "upload safe" folder are not accessible directly ; you should use a PHP script in order to send the file to a user.
So if you want to allow some of your safe files to be accessible, you need to copy them in an accessible folder or you need to create a PHP script which will send the specific files to the users.
The HikaShop download system just allow the customer to download the files they have the right too ; so a user first need to buy a product, to download his files.
