Corrupted Game Files: How to Repair

Quick Answer

To repair corrupted game files, use your game launcher's built-in verify or repair function - Steam's "Verify integrity of game files", GOG Galaxy's "Verify", or the Epic Games Launcher's "Verify" option. This automatically detects and replaces corrupted files without reinstalling the entire game. Most repairs complete within minutes.

Corrupted game files are one of the most common causes of crashes, missing textures, failed launches, and random error codes in PC gaming. They can happen after a failed update, a power interruption during download, a storage drive developing bad sectors, or even antivirus software quarantining game components it misidentifies as threats. The good news is that most launchers include a repair tool that fixes corruption without a full reinstall, saving you hours of re-downloading.

How to Verify and Repair Game Files on Each Platform

On Steam, right-click your game in the library, select Properties, navigate to the Local Files tab, and click "Verify integrity of game files". Steam checks every file against its manifest and downloads replacements for anything that fails the check. This works for the vast majority of corruption cases and is always the first step to try. On GOG Galaxy, right-click the game, click Manage Installation, then Verify and Repair. For Epic Games Launcher, click the three-dot menu on the game, then Verify. Xbox Game Pass PC games can be repaired through the Xbox app by selecting the game, clicking the three-dot menu, and choosing Repair. EA App titles use the Repair option accessible from the game's library entry. Battle.net has a Scan and Repair option under each game's options dropdown.

When Verification Does Not Fix the Problem

If verifying files does not resolve the issue, the next step is checking whether your storage drive itself is developing errors. Run Windows' built-in Check Disk tool by opening Command Prompt as administrator and running chkdsk C: /f /r (replacing C: with your game drive letter). If your games are on an SSD, check its health using CrystalDiskInfo, which is free and gives you a clear drive health status. A drive reporting caution or bad status means file corruption will continue occurring regardless of how many times you verify game files. In SA, loadshedding-related power cuts without UPS protection are a real cause of file system corruption on both HDDs and SSDs, so if corruption is recurring, check your drive health and consider adding UPS protection to your gaming setup.

Frequently Asked Questions

Q: Will verifying game files delete my save files? A: No. The verify process only checks and replaces game binary and asset files, not save data. Save files are typically stored in a separate location such as your Documents folder or cloud sync, and verification does not touch them.

Q: How long does verifying game files take? A: It depends on the game size and your storage speed. A game on an NVMe SSD takes a few minutes. A large game on a slower HDD can take 15 to 30 minutes. The launcher checks file hashes and only downloads what is corrupted, so the actual download portion is usually small.

Q: My game keeps getting corrupted repeatedly - what is causing this? A: Recurring corruption points to either a failing storage drive, file system errors on the drive, antivirus software interfering with game files, or power interruptions during writing. Run a drive health check, add your game directory to your antivirus exclusion list, and ensure your PC has stable power during game updates and sessions.
