Solution Steps

  1. 1 First, check the destination drive for errors. Open File Explorer, right-click on the drive, select Properties, go to the Tools tab, and click 'Check' under Error checking. Follow the prompts to scan and repair the drive. This is like checking the road for potholes before driving.
  2. 2 If the error occurs during network copy, try copying the file to your local drive first (e.g., C:\Users\YourName\Desktop), then copy it to the final destination. This avoids network interruptions.
  3. 3 If you're copying to a USB drive, ensure the USB connection is stable. Try a different USB port or cable. Also, avoid removing the drive during the copy.
  4. 4 If the file is large, consider using a file compression tool like 7-Zip to split the file into smaller parts. This reduces the chance of interruption.
  5. 5 Run the System File Checker (sfc /scannow) to repair any system file corruption that might affect copy operations.
