Most Windows users have, at some point, received the ‘Failed to open descriptor file error message‘. This error can be caused by a variety of factors, from a corrupted registry to malware infections.
In this article, we’ll provide some tips on how to prevent it from happening again. Let’s get started!
Move Your Game to C:\ Drive:
If you’re getting the ‘Failed to open descriptor file’ error message, it might be because your game is installed on a drive other than your C:\ drive.
Game files need to be stored on the C:\ drive for optimal performance. So, if your game is installed on a different drive, you should move it to the C:\ drive. Here’s how you can do that:
- First, close your game and exit Steam.
- Then, go to the location of your game files. The default location is C:\Program Files\Steam\steamapps\common\.
- Next, find the folder of the game that you want to move. For example, if you want to move the ‘Valorant’ game, you should find the ‘Valorant’ folder.
- After that, copy the game folder and paste it into your C:\ drive.
- Finally, launch Steam and try to run your game again.
Update Your Graphics Card Drivers:
Outdated graphics card drivers can also cause the ‘Failed to open descriptor file’ error. So, you should make sure that your graphics card drivers are up-to-date. Here’s how you can do that:
- First, close your game and exit Steam.
- Then, press the Windows key + R on your keyboard to open the Run dialog box.
- In the Run dialog box, type ‘devmgmt.msc’ and press Enter to open the Device Manager.
- In the Device Manager, find your graphics card and expand it.
- After that, right-click on your graphics card and select ‘Update driver” from the context menu.
- Now, select ‘Search automatically for updated driver software‘ to let Windows update your graphics card drivers automatically.
If Windows doesn’t find any new updates for your graphics card, you can visit the website of your graphics card manufacturer and download the latest drivers from there.
Reinstall Your Game:
If the ‘Failed to open descriptor file’ error persists, you should try reinstalling your game. This will delete all the files associated with your game, including any corrupt files that might be causing the error.
