When you purchase a game that you’ve already downloaded on your computer but from a different Steam account, you might wonder whether you’ll have to re-download the game or if you can simply use the existing files. This situation often arises if your original account was compromised or locked out, prompting a need to buy the game anew on a different account. Understanding how Steam handles game files and account restrictions can help clarify what options are available and whether a full re-download is necessary.
If you’re curious about managing multiple Steam accounts on the same device, Steam’s support documentation clarifies that you can access different accounts on a single computer, but only one at a time. The core game files are often shared between accounts if they own the same game, but configuration and custom content are maintained separately. This means you generally won’t need to re-download the entire game if the files are already present, but some conditions might trigger a re-download or verification process.
In practice, Steam may recognize existing game files and avoid redownloading them, especially if the game is installed in a common directory and the app manifest files are preserved. However, certain DRM mechanisms or different account encryption keys could cause Steam to verify or re-download parts of the game to ensure integrity. If you move or copy game data manually, you might need to initiate a re-verification or even start the download process for Steam to acknowledge the game as installed.
For users managing multiple accounts, especially on different operating systems like Mac, sharing game files can be more complex due to how each system handles user directories and permissions. Creating shared library folders and adjusting permissions can help streamline access across accounts. For example, setting up a common folder with read and write permissions and configuring Steam to recognize it as a library can minimize repeated downloads. Alternatively, moving game files manually or creating hard links between user directories can work effectively, although these methods require more technical effort.
When considering whether you need to re-download a game after switching accounts, it’s important to note that Steam does not use your personal information to verify ownership beyond the initial purchase. If you need to regain access to an account, Steam’s support team can assist by verifying your previous purchase history through credit card details or older account IDs. This process can often restore access without requiring a complete reinstallation of games.
In summary, most of the time, you can use existing game files when switching Steam accounts on the same device, provided the files are correctly recognized and no DRM or encryption conflicts occur. To reduce re-downloading, keep your game data organized and backed up, and consider sharing library folders across user accounts.
