TBH, I don't see how you can fill up a 500GB drive with everything you need. My 500GB contains everything I've ever downloaded (incl. Music, Games, Movies, etc.), all my music collections, an entire backup of my last Vista install that went tits up, every program, video and skin I've created. And it still has 185GB free
Where are the days when I struggled to fill the 12GB drive on our first PC :rolleyes: (And that was a massive HDD back then)
If you have programs you don't use very often, uninstall them, but keep user files and the installation. That way you can re-install them at any time and still keep everything
