Before you can add a download to a product, you'll first need to upload the files to your OpenCart store. To do this:
- Log into your admin area
- Navigate to Catalog > Downloads
- Click the blue plus (+) button in the top right to add a new download
When adding a download, you'll see three fields, as shown in the screenshot below. The Download Name should be something that both you and your customer will recognise, as it'll be shown in both the admin area and the customer's account.
4. Use the Upload button to upload the desired file for the download
Once you've selected the file, the Filename and Mask fields will automatically populate based on the filename. For security reasons, you should always make sure that the Mask is different to the Filename – otherwise, users could link directly to your download, bypassing the need for payment.
