Now, right-click and uninstall the game in Steam to remove it from your primary drive. I keep a dedicated game partition on my external backup drive, just so I don’t have to re-download 30 gigabytes of data every time I want to play Team Fortress 2. Ideally, you want them to be on another storage drive, either internal or external, because having two copies of the same game on a single drive isn’t particularly useful. To back up the games in the Steam common folder, just copy and paste them into another folder.
Remember, if you’ve set a custom game folder in Steam, your games will be installed elsewhere. Most of them share the same name as their respective game, but some use alternate titles or abbreviations-for example, Age of Empires II HD Edition is shortened to “Age2HD.” This folder is divided into sub-folders, one for each game installed under Steam’s master game list.
