We all started with some GB hard drive (80GB for me some 15 years ago ) and have ended up to numerous 2 and 3TB external ones.....
You cant' help it, @limfx. If you want to keep your movies, music etc, same time will come for you also, real soon!

I also keep my most important files to two same sized hard drives, as a back up, to avoid any painful loss.

I use to burn movies and series to dvds, but it is certainy tiring and boring, especially if you d/l lots of movies every...day ....!
