Hi, our Redirection settings can be used to send a buyer to a specific page, including an address at Dropbox.
However, there's no way for us to secure that address. Our redirection links expire the same as our download links, but once a buyer has clicked through they will see the location and can visit it again directly afterward or share that with others.
If that's acceptable then you can certainly use the Redirection setting in a product to send buyers to Dropbox, or even just give the normal link in your post-sale thank you email.
