Way 3: Run SFC and DISM Tools

When you face a 0x800703ee error when copying to external storage, you can also try the SFC and DISM tools. They are the built-in tools in Windows that can help diagnose and repair system file issues.

To use these tools, you should first right-click on the "Start" button and choose "Windows PowerShell (Admin)" or "Command Prompt (Admin)" from the menu.

Now, to run SFC, follow these steps:

  • After you click on the command prompt, type sfc /scannow. Press Enter.
  • The SFC tool will then scan and repair any corrupted or missing system files that might be causing the error.
  • Once the scan completes, you'll see a message indicating if any issues were found and addressed.

If the SFC tool doesn’t resolve the issue or if it states that it found corrupt files but couldn't fix them, you can use the DISM tool.

Do these steps:

  • In the same command prompt, type DISM /Online /Cleanup-Image /RestoreHealth and hit Enter.
  • The DISM tool will now work to fix any remaining system file issues. The DISM process can be more time-consuming than the SFC scan, so it's essential to wait until it's finished.

After the DISM process is completed, it's a good idea to run the SFC scan one more time to ensure all issues are resolved.

Once both scans are done, and any potential issues are fixed, you will be able to use transfer files again!
