What should I do when I encounter the error message saying ‘file 8377 is corrupted Windows 10’?
Recently, I encountered a frustrating problem on my Windows 10 PC. Out of nowhere, an error message popped up stating that ‘file 8377 is corrupted’. This was alarming because I was in the middle of working on an important project. I tried reopening the file, but the error message kept appearing. I have no idea what caused this corruption, and now I am worried that I might lose critical data. My antivirus program didn’t detect any issues, and I haven’t made any unusual changes to my system recently. I need to understand why this error occurred and what I can do to prevent further issues.

To rectify the issue of a corrupted file on your Windows 10 system, one effective method involves using specialized third-party software designed to repair corrupted files.
Software such as Stellar Phoenix Windows Data Recovery or Recuva can be incredibly useful. Here’s how you can use Stellar Phoenix:
- Download and install the Stellar Phoenix software from its official website.
- Open the program and select ‘All Data’ for a comprehensive scan.
- Choose the location of the corrupted file and click on ‘Scan’.
- The software will scan and list all the recoverable files. Select the corrupted file 8377.
- Click on ‘Recover’ to retrieve and save the file to a secure location.
In addition, you can try using the Windows DISM tool:
- Open Command Prompt with administrative privileges.
- Type
DISM /Online /Cleanup-Image /RestoreHealth
and pressEnter
.
This command scans for issues and repairs Windows images, which might resolve the corruption.
These methods should assist you in fixing the corrupted file and prevent data loss.

Here is what I recommend doing to solve the issue of a corrupted file on your Windows 10 machine based on past experiences in IT:
- Check for Windows Updates:
- Go to
Settings > Update & Security > Windows Update
. -
Click on
Check for updates
to ensure your system has the latest updates that may include fixes for such corruption issues. -
Run Disk Cleanup:
- Type
Disk Cleanup
into the Windows search bar and select the drive containing the corrupted file. -
This will remove unnecessary files and potentially resolve miscellaneous file corruptions.
-
Check Event Viewer:
- Open Event Viewer by typing
eventvwr.msc
in the Run dialog. -
Look for warnings or error messages related to file operations or disk issues.
-
Overwrite Corrupted File:
-
If you have another copy of the corrupted file, or if it’s downloadable, try overwriting it with a new, uncorrupted version.
-
Ensure Adequate Power:
- File corruption can sometimes occur due to sudden power losses. Ensure your computer is connected to a stable power source or use a UPS.
By systematically going through these steps, most file corruption issues can be resolved without resorting to more drastic measures.

To fix the ‘file 8377 is corrupted’ error on Windows 10, here’s what I recommend based on my experience:
Check if you have a recent backup of the corrupted file. If so, restore that backup version to overwrite the corrupted file. It’s always good practice to take regular backups to avoid such problems.
If there is no backup, start by using the built-in Windows System Restore point. This function can help revert your system to a state before the file got corrupted, potentially resolving the error:
- Go to the Start Menu and search for “System Restore.”
- Select “Create a restore point” and click on the “System Restore” button.
- Choose a restore point before the corruption issue started.
Sometimes, file corruption occurs due to hardware issues. Try another storage device, like moving the file to an external hard drive or USB stick to check if it’s readable. If the file opens without issues on another storage device, you may need to check for hardware failures on your current drive.

It sounds like you’re encountering a frustrating issue with a corrupted file on your Windows 10 system. To address this, I would suggest trying the following steps:
-
Use File Explorer: Sometimes, simply copying the corrupted file to a different directory or drive can clear up the corruption.
-
Run the CHKDSK Tool:
- Press
Windows + X
and selectWindows PowerShell (Admin)
. - Type
chkdsk /f C:
and pressEnter
. Replace ‘C:’ with the drive letter where the corrupted file is located. -
Follow the instructions that appear to fix disk errors.
-
Use Windows System File Checker:
- Press
Windows + X
and selectCommand Prompt (Admin)
. -
Type
sfc /scannow
and pressEnter
. This will scan and repair corrupted system files. -
Windows File Recovery Tool:
- Download and install the Windows File Recovery tool from the Microsoft Store.
-
Run the tool to attempt recovery of the corrupted file.
-
Restore from Backup: If you have a recent backup of your files, restoring from it may resolve the issue.
By trying these methods, you should be able to address the corruption and continue working on your project.
