A game I played last night suddenly disappeared from my computer, where did 80 GBs of files even go?

Hi,Nihat ErenEkinci.

Thank you for posting to the Microsoft community.

From your description, I learnt that when you finished playing Remnant II, you shut down the game and your computer, and when you started Windows 11 again, you found that the game had disappeared, and I understand your confusion about this problem.

Please check if the space on the hard disc where you installed the game has changed, if not, search for the game in ‘This PC’ or check the recycle bin.

You can try to use a disc detection tool:

1. Open File Explorer and navigate to This PC.

2. Locate the drive you want to scan. Right-click on the drive and select Properties from the menu.

3. Navigate to the Tools tab, and then click the Check button.

4. Click Scan Drive to start the scan.

Run powershell as administrator, use the cd command to get to the directory where the game is located and enter the following code:

Add-AppxPackage -path . \appxmanifest.xml -register 

Then restart the computer or the Xboxapp app.

Disclaimer: Please save your current data before restarting your computer.

Are you using an external hard drive? If you are using an external hard drive, please try unplugging the drive and plugging it in again, then add the game path from the Xbox app.

The My Library and Cloud Games sections of the Xbox app on Windows allow you to browse and launch games in your collection from a single location.

There are users in the forums who have experienced issues similar to yours, and some of them have resolved their issues with this solution, so you can try it as well:

XGP Installed Games Disappear from the List; Game Store clicks on the game to show that there may be a problem with the app, please try again later - Microsoft Community
