I don’t know if this is the easiest way, but it has worked well for me. I have a folder on my computer set up to be accessible from the local network. When I need to put some files on the deck, I switch it into desktop mode where I have a shortcut to the network folder. Then I just take the files out and put them wherever I need them on the deck.
As far as I understand it, the node is more useful for car routing, since it marks the exact point on the road where the intersection crosses, while the way is more useful for pedestrian routing, where the actual path to be traveled is more relevant. I agree that it seems redundant, but for all I know, car routers might totally ignore any pedestrian footways, which would prevent them from filling in the crossing data on the fly.
