Overview

In this article, we’ll focus on resolving the issue described as: “The volume for a file has been externally altered so that the opened file is no longer valid. [ERROR_FILE_INVALID (0x3EE)]”. This error, identified by the error code Error Code 1006, can impede your system’s performance, and here’s how you can fix it.

Identifying the Problem

Error Code 1006 arises when a file has been modified outside of the standard Windows environment, such as through a third-party application or external storage device. This can occur when:

• Files are transferred or copied between different storage devices using drag-and-drop rather than proper copy/paste functions.
• Files are modified on a network-attached storage (NAS) device or over a network without proper synchronization.
• Anti-virus software scans and quarantines files, modifying their structure.
• System crashes or power outages abruptly interrupt file operations.

Common Fixes

Solution 1: Restart the Computer

Restarting the computer can resolve temporary glitches that may have triggered the error. This action closes all open programs, including any that may have been modifying the file in question.

Solution 2: Check File Permissions

Ensure that you have sufficient permissions to access and modify the affected file. Right-click on the file, select “Properties,” and navigate to the “Security” tab. Verify that your user account has “Read/Write” or “Full Control” permissions.

Solution 3: Run CHKDSK

CHKDSK is a utility that scans and repairs file system errors. Open Command Prompt as an administrator, then type the following command:

chkdsk /f /r

Press Enter and allow CHKDSK to complete its operation. It will scan and fix any detected file system errors.

Solution 4: Update Device Drivers

Outdated drivers can sometimes lead to file handling issues. Update the drivers for your storage devices, especially if you have recently connected a new external storage device.

Advanced Troubleshooting

Solution 5: Disable Anti-Virus Software

Temporarily disable your anti-virus software and try to access the file again. In some cases, anti-virus software can interfere with file operations and trigger Error Code 1006.

Solution 6: Use System Restore

If the issue persists, consider using System Restore to revert your system to a point before the error occurred. This will undo any recent changes that may have caused the problem.

Solution 7: Reinstall the Operating System

As a last resort, if all other solutions fail, you may need to reinstall your operating system. This will completely wipe your hard drive and reinstall Windows, resolving any underlying issues that could be causing the error.

Conclusion
