How to Verify and Repair Game Files on Steam.
A game that crashes on launch, shows missing textures, or freezes on a loading screen isn’t always broken beyond repair. Often, a few game files are damaged or missing. Steam has a built-in tool that finds and fixes them in minutes. Here’s how to use it.
What “Verify Integrity” Does
Steam keeps a record of every file it installs for a game. When you verify, it compares the files on your drive with the correct versions on its servers. Anything damaged or missing gets downloaded again. You don’t have to reinstall the whole game, which saves a lot of time and data.
How to Verify Game Files, Step by Step
- Open Steam and go to your Library.
- Right-click the game and choose Properties.
- Select the Installed Files tab. On some versions, it’s called Local Files.
- Click Verify integrity of game files.
- Wait for Steam to finish. It can take a few minutes.
You can also click the gear icon on the game’s page to find the same option. When it finishes, Steam tells you how many files it fixed. Then launch the game and test it.
When You Should Use It
Try verifying files in these situations:
- The game crashes at startup or while loading.
- Textures or models are missing, such as invisible walls or black objects.
- You hit a power cut or forced shutdown during play.
- An update failed or stopped halfway.
- You moved the game between drives.
It’s a quick, low-risk first fix for most of these problems.

“Some Files Failed to Verify”: Is That a Problem?
Usually, no. Steam notes that one or more files failing to verify can be safely ignored in most games. These are often local configuration files that Steam isn’t meant to replace. Worry only if the game still has problems afterwards.
What About Mods?
Verification checks the files Steam installed. Extra files from mods or tools are ignored, and Steam doesn’t remove them. That means a broken mod can still cause crashes after a clean verification. If problems continue, try disabling your mods and testing the game without them.
If Verifying Doesn’t Work
Try these steps in order:
- Restart your PC and test again.
- Repair your Steam library folder. Go to Steam, then Settings, then Storage, and use Repair Folder on the drive that holds the game.
- Check your security software. Antivirus can sometimes block or flag game files. Rather than switching it off, try adding Steam and the game’s folder to its exclusions list.
- Close your VPN. It can interrupt downloads and cause repeated errors.
- Update your graphics drivers. Some crashes come from drivers, not game files.
- Reinstall the game. If nothing else works, a fresh install is the final option. Your saves are safe if Steam Cloud is on.
Other Launchers Have Similar Tools
If you play outside Steam, the idea is the same:
- Epic Games Launcher: Open the three-dot menu, choose Manage, then Verify.
- GOG Galaxy: Open the game’s settings, then choose Manage installation, then Verify or Repair.
- Battle.net: Click the gear icon, then Scan and Repair.
- Ubisoft Connect: Open the game’s Properties, then Verify files.
The Bottom Line
Verifying game files is one of the fastest fixes in PC gaming. It takes a few clicks, costs almost no data, and solves many crashes and missing-texture problems. Try it before you reinstall anything. If it doesn’t help, work through the follow-up steps, and your issue is likely to turn up along the way.
FAQs
Does verifying game files delete my save data?
No. It only checks and replaces the game’s installed files. Your saves stay safe, especially with Steam Cloud on.
How long does verifying take?
Usually one to fifteen minutes, depending on the game’s size and whether you use an SSD or hard drive.
Is it a problem if a few files fail to verify?
Normally not. Steam says it can be safely ignored in most games, since these are often local config files.
Does verification fix broken mods?
No. Steam ignores files added by mods, so disable or remove mods to test whether they’re causing the problem.
Can I verify all my Steam games at once?
No. Verification works one game at a time.
