The problem can occur if you decide to clean install Windows and take a backup of the Steam app folder containing your game files and other data. You then move it back to the Steam installation folder only to have Steam to re-download all the game data back again. So, if Steam is not detecting installed games, continue reading the guide below and discover the best methods to eliminate this problem quickly.

Why is Steam not recognizing the installed game?

A few factors can cause Steam not to recognize the installed game issue. Below are some of the prominent causes:

Unrecognized game files: If Steam is not detecting your installed games, it might be because it does not recognize the game files again. The solution to this is to reinstall these games. Insufficient space: In some cases, this issue might be caused by insufficient space on your primary drive. You can fix this by moving some games to an external drive and recognizing them from there.

What can I do if Steam doesn’t recognize installed games?

1. Reinstall the games without downloading

If Steam fails to recognize any of the installed games, it will allow you to install them again. If you have the game data in the Steam apps folder, you can force Steam to recognize the games by initiating the game’s installation.

2. Add the Steam Library folder manually

Steam, by default, stores the game data in the Steamapps folder on the installation disk. If you had a custom location where the game data was stored, you could try to add the location in the Steam app to fix this issue.

3. Recognize Games from a new drive

If your main drive (steam default installation location) does not have enough space to install all the games, you can move the game data to a new hard drive and then add the Game Library Folder manually in the Steam app. In the steps above, you can find how to do it if you want your games to be in the D:/games directory. Thus, you’ll need first to create a subdirectory named Steamappscommon. The folder structure will look like this:D:\Games\steamapps\common SPONSORED Once the subdirectory is created, move all the games to the newly-created directory. After moving the games, the game directory will look like this:D:\Games\steamapps\common\Assassin’s Creed IV Black Flag D:\Games\steamapps\common\Counter Strike Global Offensive Exit Steam and relaunch it. The app will scan the newly selected Library folder and show all the games as installed.

4. Use .acf Cache to force recognize Steam games

If you have taken the Steamapps folder backup with all the game data, you can use the Steam cache files to force Steam to recognize the installed games from the game data. In other words, you make Steam scan for games that you own. If everything goes right, all the games that you had previously installed will appear as installed. However, if an update is required, proceed with it. That’s about it for Steam not recognizing the installed game issue. With the solutions in this guide, you should be able to get Steam to recognize your games even on an external drive. Are you facing similar issues, like the Steam game not showing up in the library?
