How to Verify Game File Integrity (Steam, Epic, GOG, Xbox)

A game that crashes on launch, shows missing texture errors, or hangs mid-session may have one or more corrupted or incomplete files. Every major PC launcher has a built-in file verification tool that compares your local files against the official copy and re-downloads only what's broken.

Steam

1. 1
   Open Steam and go to your Library.
2. 2
   Right-click the game and choose Properties.
3. 3
   Click the Installed Files tab, then Verify integrity of game files.
4. 4

   Steam will compare your files against the server. The process takes 1–10 minutes depending on the game size and your disk speed.

5. 5

   When it finishes, Steam shows how many files were validated and whether any were re-downloaded. Relaunch the game.

Epic Games Launcher

1. 1
   Open the Epic Games Launcher and go to your Library.
2. 2
   Click the three-dot menu (⋯) on the game's tile.

4. 4
   Wait for the scan to complete, then relaunch.

GOG Galaxy

1. 1
   Open GOG Galaxy and find the game in your library.
2. 2
   Click the settings cog next to the Play button.
3. 3
   Choose Manage Installation → Verify / Repair.
4. 4
   GOG will check all files and repair any issues.

Xbox App / PC Game Pass

1. 1
   Open the Xbox app on Windows.
2. 2
   Go to My Library, find the game, and click the three-dot menu.
3. 3
   Select Manage → Files → Verify and repair.

Common follow-up steps

• Antivirus false positive: Security software sometimes quarantines game files during or after installation. Add the game's folder to your antivirus exclusions, then run verification again so the missing files are restored.
• Disk health: Frequently corrupted files may indicate a failing drive. Run chkdsk C: /f (replace C: with your game drive) or use your SSD manufacturer's health tool to rule this out.
