Imagine what you could save for 10 or 20 games.A little tool that is able to list every redistributable package stored on your Steam directories, and allows you to remove them. Yes, it is about a third of the game files size, and they are not removed by Steam. For each of them, you can count 100MB for the DirectX redistributable package. An example : install the first complete season of Sam & Max (6 episodes) : every episode is about ~300MB. The Steam application allows you to download games from the Internet and install them, but what about these redistributable packages ? You probably saw they are installed the first time you launch your game, OK, but what happens to these files when they go wasted ? The answer is very simple : Steam doesn't delete them.

They were installed from the CD/DVD, and those installers didn't stay on your hard drive.

When you installed a video game from a CD or a DVD, you installed some redistributable packages too : DirectX, Games For Windows Live Redist, VC Redist, Rapture3D, NVidia PhysX Redist, etc.
