Digital Copies.

[Tom Bars]

I have 60 or so blu-rays some of which have the digital copy option. I have not tried that out yet due to insufficient room on my computer. I am just curious, i usually throw away all that paper/insturction manual spam inside the bluray, you know it just gets annoying, but my friend told me i should have kept all that because that stuff has a code on it that allows you to get it on the computer. Is it still possible to get all of the digital copies onto the computer without all the manual/code that it came with?
