How to verify game files on Steam

If your Steam game isn’t working as you expected, whether it’s failing to load objects correctly or is constantly crashing, then Valve recommends that you verify the files of your chosen game. 

By verifying your files, Steam can check whether all of the required game files have been correctly installed on your PC. Having just one file missing could create detrimental effects on your experience.

So what are the steps you need to take to verify your game files on Steam? We’ve listed them all below, so read on for the full breakdown. 

What you’ll need

  • A Steam account
  • Purchased game on Steam 

The short version

  1. Click on your Steam game library 
  2. Right-click on your chosen game
  3. Select Properties 
  4. Click on Installed Files
  5. Select Verify integrity of game files
  6. Wait for the process to complete
  1. Step

    Click on your Steam game library

    Open up your Steam account, and then click on Library on the second highest row. You should find it sandwiched between Store and Community.

  6. Step

    Wait for the process to complete 

    You’ll now need to wait for this process to complete, which took a couple of minutes in our experience. Steam warns not to run any other intensive applications in the background during this process, and that you should only verify one game at a time to avoid complications. 

    Once it hits 100%, your game files should be verified, and any missing game files should automatically be added to your PC.

Why is my game still not running properly?

If your game still isn’t running properly after verifying your game files, there may be another issue. Double check that your PC meets the technical requirements of the game, and that you have all of the latest graphics drivers installed. 

It’s also worth checking online whether anyone else is experiencing similar issues for that specific game, especially if it only recently became available.

Why won’t Steam verify my game files?

If the verification process won’t run, it may be because your internet connection isn’t strong enough, as Steam requires a consistent connection to complete the process. Double check your internet connection, and then try again.
