Adding Downloadable Spec and Documentation to Product

[truevision.co.za]

Hello All

I have search the fact for downloadable data on products to no avail.

I have a physical product which I would like to add some documentation to, specs, manuals and the like.

Is there an easy way of doing this? If so could I make all my products default to this way of doing things?
