What does it mean to validate or verify game files on Steam?
Verify file integrity Steam compares the files you have installed locally on your computer with the official files stored on its servers. The goal is to identify if any files are missing, damaged, modified, or corrupted, and to resolve these issues in the most automated way possible. If it detects any problematic files, Steam replaces, repairs, or re-downloads only what is necessary., saving time and avoiding complete reinstallations.
This feature is especially useful after a failed update, a power outage, if your antivirus has interfered with the game files, or simply if you experience errors when launching the game. It's also a recommended option before reinstalling the entire game, as it often resolves the issue in just a few clicks and without losing any configuration data.
It's worth noting that some games have local configuration files that may not exactly match the originals, which is completely normal. Steam may report files that fail to verify, but in most situations these are custom elements (language, controls, saved games) that do not affect overall performance.
When should you use Steam file verification?
There are several circumstances where validating your game files is the most straightforward and secure solution:
- Errors or crashes when starting a game: If the title doesn't start, crashes immediately, or displays error messages related to missing or corrupted files.
- Updates that do not apply correctly: If after an update the game stops working or has errors that did not exist before.
- Strange gameplay changes: Textures not loading properly, missing sounds, sudden graphical issues, or any unexpected changes.
- Intervention of other programs: If an antivirus, system optimizer, or third-party program has modified, deleted, or quarantined files in the game folder.
- Before reinstalling: Often, reinstalling the entire game isn't necessary. A simple verification process can fix common issues.
In all of these cases, verification is usually the first recommendation from both veteran users and Steam support, as it is a quick, reversible process that does not result in the loss of saved games or customized settings (with very specific exceptions).
Steps to verify the integrity of game files on Steam
The procedure is very simple and is integrated into the Steam application itself. I'll explain below. how to do it step by step clearly, following the instructions of official support and practical advice from the community:
- Open the Steam client on your computer and log in with your account.
- Enter the section Library and locate the game that is causing problems.
- Right click on the game name and select the option Properties in the drop-down menu.
- In the pop-up window, click on the tab Installed files or in some versions simply Local archives.
- Push the button Verify the integrity of the game files…
- Steam will begin the comparison and review process. This may take from a few seconds to several minutes, depending on the size of the game and the speed of your hard drive.
- When the check is complete, if everything is correct, it will inform you. If it detects corrupt files, it will automatically download and repair them.
- The verification window will close automatically upon completion of the process.
Tip: It's recommended to close the game before performing the verification and avoid intensive use of your computer until it's finished. If you have multiple discs or the game is installed on a different drive than your primary drive, make sure you select the correct game.
Why might Steam fail to verify some files?
During verification, Steam often reports that "one or more files could not be verified." In practice, this is usually completely normal and shouldn't cause any concern if the game runs normally after the process. These files are usually local configuration files, user preferences, or files dynamically created by the game itself., which is neither necessary nor advisable to modify or restore to its original state.
In most cases, these files have no direct connection to the operating issues, and their presence shouldn't hinder you. Only in rare cases, when dealing with mods or fundamentally altered files, may it be necessary to manually delete them or restore the entire game folder.
Advantages of validating files versus reinstalling the game
Many users automatically choose to reinstall a game when they encounter a problem, but validating the files is actually a much faster and more effective option in most cases:
- Save time: Only repair or download the corrupted files, instead of downloading the entire game again.
- You don't lose data: Saved games and most settings remain intact.
- Avoid further complications: No need to manually delete folders or deal with potential installation errors.
Therefore, unless Steam or the game itself specifically tells you otherwise, It is always a good idea to try file verification first. before proceeding with a complete uninstall/reinstall.
What to do if verification doesn't solve your problem?
Although file verification is very effective, there are times when some errors persist even after the process. If this is your case, keep the following in mind:
- Check the integrity of the hard drive: Sometimes the source of the error is physical or logical failures on your disk. Use diagnostic tools (such as CHKDSK in Windows).
- Update drivers and operating system: Keeping your graphics card drivers, Windows, or even Steam up to date is critical to avoid unexpected conflicts.
- Temporarily disable antivirusSome antivirus programs may block game files. Try temporarily disabling your antivirus and rechecking.
- Reinstall the game as a last resort: If nothing works, perform a complete uninstall and reinstall the game by downloading it from Steam.
