Moving your entire Steam installation is a guide in and of itself. Just follow Valve's step-by-step instructions if you want to move all of Steam to a whole new drive.
Read on for secret game management options, tips on how to get the most from Steam's Jump List, and the really advanced stuff.
Batch install or uninstall games
A recent update made it much easier to reinstall all your games if you do need to move Steam to a new computer. Yes, Steam can now install or delete games in bulk.
Open your Steam library in Detail or List View and select the games you'd like to install by Crtl + clicking on each. (The games you chose will appear highlighted.) When you're done, simply right-click on one of the games and select the Install option. Boom! You'll be greeted by bulk installation options for the entire mass of games.
Conversely, you can also select multiple games that are already installed on your hard drive, then right-click and choose Delete Local Data to wipe them all off your PC in one fell swoop.
Remote game installation
You can also remotely install games you buy when you're out and about, assuming your home PC is on, connected to the Internet, and logged into Steam. It's a welcome feature when you go on an impulse buying binge at work or on public transportation.
To install a game from afar, first log into your Steam account on the Steam Community website. When you're in, click your Steam account name in the list of options at the top of the page, then click Games option the right-side options pane that appears. In your Games page, open the All Games tab to view your entire library. Click the Installation icon to the right of the listing for the game you'd like to install and it'll promptly begin downloading on your home computer.
Hide games from your library
In a world where Summer Sales and Humble Bundles threaten to swell backlogs to ridonkulous proportions, gamers have pleaded for a way to hide games from their libraries for years. And finally--finally!--Valve has delivered, though Steam doesn't advertise the handy-dandy feature in any way.
To hide a game in your library, right-click on it and choose Set Categories. Then, check the "Hide this game in my library" box and click OK. Done! The game disappears from your library, banished to a "Hidden" filter accessible only by clicking the small Games button next to the library's search box and clicking--you guessed it--"Hidden." There, you can dive back into the game's category options and un-check the "Hide this game" box if you want to return it to the light.
