In this article, we'll delve into the possible causes of corrupted replays, explore the different methods for fixing them, and provide tips on how to prevent this issue from happening in the future.
Understanding the Causes of Corrupted Replays

Before we dive into the solutions, it’s essential to understand what might be causing your League of Legends replays to become corrupted. Some common reasons include:
- Filesystem Errors: Issues with your computer’s filesystem, such as bad sectors or corrupted files, can lead to replay corruption.
- Insufficient Disk Space: If your hard drive is running low on space, it may cause issues with writing and storing replay files, resulting in corruption.
- Software Conflicts: Other programs running in the background may interfere with League of Legends, causing replays to become corrupted.
- Outdated Drivers or Software: Using outdated graphics drivers, operating systems, or other software can lead to compatibility issues, resulting in corrupted replays.
Method 1: Checking for Filesystem Errors
To fix corrupted replays, start by checking your computer’s filesystem for any errors. You can use the built-in Check Disk (chkdsk) utility in Windows or the Disk Utility in macOS to scan for and fix any issues.
Operating System | Utility |
---|---|
Windows | Check Disk (chkdsk) |
macOS | Disk Utility |

Run the utility and follow the prompts to scan your hard drive for errors. If any issues are found, the utility will attempt to fix them, which may resolve the corrupted replay problem.
Method 2: Clearing the Replay Cache

League of Legends stores replays in a cache folder, which can sometimes become corrupted. Clearing the cache folder may resolve the issue. To do this:
- Close League of Legends and any other related programs.
- Navigate to the League of Legends installation directory (usually C:\Riot Games\League of Legends).
- Delete the entire “Replay” folder.
- Restart League of Legends and try to watch a replay again.
Method 3: Updating Drivers and Software
Outdated drivers or software can cause compatibility issues, leading to corrupted replays. Ensure that your graphics drivers, operating system, and other software are up to date.
For graphics drivers, you can visit the manufacturer’s website (e.g., NVIDIA or AMD) and download the latest drivers. For operating system updates, go to the settings or control panel and check for any available updates.
Key Points
- Check for filesystem errors using built-in utilities.
- Clear the replay cache folder to resolve potential corruption.
- Update graphics drivers and software to ensure compatibility.
- Run League of Legends as an administrator to resolve potential permission issues.
- Consider reinstalling League of Legends if all else fails.
Method 4: Running League of Legends as Administrator
Sometimes, permission issues can cause problems with replay files. Try running League of Legends as an administrator to see if this resolves the issue.
Right-click on the League of Legends executable (usually located in the installation directory) and select “Run as administrator.” This will launch the game with elevated permissions, which may help resolve any permission-related issues.
Method 5: Reinstalling League of Legends
If none of the above methods work, you may need to reinstall League of Legends. This will reset the game’s settings and potentially fix any underlying issues causing corrupted replays.
Before reinstalling, make sure to back up any important files, such as your replay files or game settings. Then, uninstall League of Legends and download the latest version from the official website.
