If by any chance Steam doesn’t recognize any of the games, it’s likely that the games haven’t been installed.

Here are the steps you need to follow.

Open the Steam client and log in with your credentials.
Tap on the Games option present at the top section.
Choose View Games Library.
On the following page, you will find a list of all the downloaded and installed games. The list also includes games that Steam is unable to recognize.
Choose the game that Steam is not able to recognize and click on the Install option.

Now, Steam will use the stored game files to forcefully install the game. Once done, restart Steam, and check whether your game is listed or not.

2] Choose New Installation Drive

Steam will fail to install the game if the default installation drive doesn’t have free space. Thankfully, you can change the Steam default installation location manually. Here are the steps you need to follow.

Choose Settings.
In the settings menu, choose the Download option present at the left panel of the screen.

Choose your new installation folder.

That’s it. Relaunch Steam and check if the problem is fixed.

3] Force recognize Games using .acf Cache

If Steam is not recognizing the game, even if you have manually installed it using the above method then you will have to use the Steam cache data to recognize the games. Here are the steps you need to follow.

Navigate to the place where you have stored all the Steam data. By default, it is C: > Program Files (x86)> Steam > Steamapps folder
Open the Steam client, look for the games that are not installed. Choose the uninstalled games, and tap on the Install option.
Steam will take some time to recognize all the existing files.
Pause the update process and exit Steam.
Go to C: > Program Files (x86)> Steam > Steamapps folder and select all the .acf files.
Copy all the .acf files, paste them anywhere else other than the Steamapps folder.
Open the Steam client and click on the Library. In the library section, you will see that the unrecognized game is denoted by the Uninstalled option.
Close Steam client.
Move all the .acf files back to the Steamapps folder.

That’s it. Open Steam and go to the Games library section. Tap on the resume update option on all the games that you paused before. Once the update process is complete, you will see the game listed on Steam.
