Encountering the error message “An unexpected error is preventing you from copying this file” on Windows 10 can be frustrating, especially when urgent file transfers are needed.

Continue reading to learn how to fix this common Windows 10 problem efficiently.

Understanding the Causes Behind the Error

The “unexpected error” message typically stems from various underlying issues within Windows 10. Common causes include:

  • File/Folder Permissions: Insufficient permissions can block file operations, especially if files are located in protected or system folders.
  • File Locks or Use by Other Programs: When a file is open or used by another application, Windows prevents copying to avoid conflicts.
  • Corrupted System Files or Disk Errors: System corruption or disk issues can interfere with file management processes, leading to errors.
  • Antivirus Interference: Overprotective antivirus software may mistakenly block file operations, perceiving them as threats.
  • Network or External Drive Issues: Problems with external drives or network restrictions can also manifest as copying errors.

    Step-by-Step Solutions to Fix the Error in 2025

    Addressing this error requires a methodical approach. Follow these practical steps to resolve the issue effectively:

    1. Verify and Adjust File Permissions

    Often, permission issues prevent file copying. Ensure you have the necessary rights:

    1. Right-click the problematic file or folder and select Properties.
    2. Navigate to the Security tab.
    3. Click on Edit to modify permissions.
    4. Select your user account and check “Full Control”.
    5. Click Apply and then OK.

    This grants you full access, which can eliminate permission-related errors.

    2. Close Background Applications and Use Safe Mode

    If the file is in use, close all applications that might be using it. To identify and terminate processes:

    1. Open Task Manager (Ctrl + Shift + Esc).
    2. Locate applications that might be accessing the file.
    3. Right-click and select End Task.

    Alternatively, boot into Safe Mode—a minimal environment that prevents most processes from running:

    • Press Windows + R, type msconfig, and hit Enter.
    • Go to the Boot tab and check Safe boot.
    • Click OK, restart your PC, and attempt copying again.

    Advanced Fixes for Persistent Issues

    If the above steps don’t resolve the issue, consider more advanced troubleshooting:

    • Run System File Checker (SFC) to repair corrupted system files:
    sfc /scannow

    Open Command Prompt as Administrator:

    1. Type cmd in the Start menu search bar.
    2. Right-click on Command Prompt and select Run as administrator.
    3. Enter the command above and press Enter.

    This process can fix underlying system issues causing file operation errors.

    • Check Disk for Errors to ensure your storage device is healthy:
    chkdsk /f /r

    Run this command in an elevated Command Prompt and follow the prompts, especially if your drive shows signs of errors.

    Conclusion

    Fixing the “unexpected error” while copying files on Windows 10 in 2025 involves verifying permissions, ensuring files aren’t in use, and repairing system or disk errors. By systematically applying these solutions, you can resolve the problem efficiently. Remember to maintain regular system health checks in the future to prevent similar issues and enjoy seamless file management on your Windows PC.
