League of Legends (LoL) is one of the most popular multiplayer online battle arena (MOBA) games, known for its strategic gameplay and highly competitive environment. One of its key features is the ability to save and watch replays of past matches. This allows players to analyze their gameplay, review key moments, and create content for streaming or sharing with others.
What Are League of Legends Replay Files?
League of Legends saves replay files in a specific format (.rofl) that allows users to rewatch matches from within the client. These files are not standalone video files but instead contain match data that the game engine reconstructs when played. Since they are linked to specific game patches, any game update can potentially make older replay files unplayable.

Common Reasons for Replay File Corruption
Several factors can cause a League of Legends replay file to become corrupted, including:
Game Updates/Patch Changes – Replays often stop working after a new patch update.
Incomplete Downloads – If a replay was not properly saved, it may not function correctly.
File System Errors – Disk errors can corrupt files stored on your computer.
Third-Party Software Conflicts – Some programs may interfere with replay functionality.
Unexpected Game Crashes – A crash during or after saving a replay can lead to corruption.
Manual File Tampering – Editing or renaming the .rofl file improperly can render it unreadable.
Methods to Fix a Corrupted League of Legends Replay File
1. Restart Your Game and Try Again
Sometimes, a simple restart can resolve minor glitches affecting the replay. Close the League of Legends client completely, restart your computer, and try opening the replay again.
2. Check if the Replay Is Compatible with the Current Patch
LoL replays are version-dependent. If the game has updated since the replay was recorded, it may no longer be compatible. In this case, try these solutions:
Revert to an older patch (if possible) using a third-party tool like LoL Archive.
Check forums or community groups to see if others have found a way to run old replays.
3. Verify the Integrity of Game Files
If the game itself has corrupted files, your replays may not load properly. To verify and repair League of Legends:
Open the Riot Games client.
Click on the League of Legends tab.
Navigate to Settings > General.
Find the Repair option and let the process complete.
This can resolve corruption issues affecting game data.
4. Redownload the Replay File
If the original replay file is corrupted, try deleting it and downloading it again:
Open the League of Legends client.
Navigate to Match History in your profile.
Locate the match and click Download Replay.
Try playing the newly downloaded file.
5. Move the Replay File to a Different Location
Sometimes, file system errors can cause corruption. Try moving the replay file to a different location:
Navigate to the replay folder:
makefile
复制编辑
C:\Users\YourUsername\Documents\League of Legends\Replays\
Copy the corrupted replay to another folder (e.g., Desktop).
Try opening it from the new location.
6. Open the Replay in a Different User Profile
If the replay works on another user account, the issue may be related to your current Windows profile.
Create a new Windows user account.
Log in and install League of Legends.
Try opening the replay in the new profile.
7. Use Third-Party Tools to Convert or Repair the Replay
Panda Assistant also offers a preview function, enabling users to view recoverable files before restoring them. This feature helps ensure that you only recover the data you need, saving time and storage space. Additionally, the software prioritizes data integrity, ensuring recovered files maintain their original quality and structure.
The recovery process with Panda Assistant is straightforward. Users simply select the drive or location to scan, initiate the scanning process, and review the recoverable files. With just a few clicks, lost data can be restored to a secure location. Its user-friendly design ensures that even those with minimal technical knowledge can successfully recover their files.
8. Restore the File Using Windows File Recovery
If the replay file was recently deleted or modified, you can try restoring an earlier version:
Right-click the replay file and select Properties.
Go to the Previous Versions tab.
Restore an earlier version of the file if available.
Alternatively, use Windows File Recovery (Command Prompt tool) to scan for deleted versions.
Preventing Future Replay File Corruptions
To minimize the chances of losing your valuable replays in the future, consider the following precautions:
1. Regularly Back Up Important Replays
Since League of Legends replays can become unusable after patches, save a copy in a separate folder. You can also record them as videos using software like:
OBS Studio
NVIDIA ShadowPlay
Bandicam
2. Avoid Interrupting the Game While Saving a Replay
To prevent incomplete downloads, avoid closing the game or shutting down your PC while saving a replay.
3. Keep Your System Updated
Ensure that your operating system, drivers, and League of Legends client are always up to date.
4. Check for Disk Errors Regularly
Run the following command in Command Prompt to check for disk errors:
sh
chkdsk /f /r
5. Use Cloud Storage for Replay Backup
Upload important replays to Google Drive or Dropbox to keep them safe from corruption.
