How to verify your game files on Steam

Why would you need to verify your game files? If you are having issues with your game on Steam, it may be caused by corrupt or missing game files. This can cause glitching, lagging, crashing or other unexpected issues.

When you verify your game files, the Steam client determines if this is the cause and replaces any game files that are missing or corrupted.

• Restart your computer and launch Steam
• Next, locate your game in your library and either right-click on the game or click the gear icon.
• From the drop-down menu, select Properties.
• Select the Local Files tab and click the Verify integrity of game files... button.
• Steam will verify the game's files. (This process may take several minutes)
• Launch your game after Steam completes the process.

Important: One or more files may fail to verify. This is normal for most Steam games. The files that fail to verify are local configuration files that should not be replaced as part of this process. You can safely ignore this message.

Warning: Do not run the verification process while performing other system-intensive processes, such as defragmenting your hard drive or scanning for viruses. Do not run this process for multiple games at the same time.
