Robocopy is a powerful utility in Windows that allows you to mirror directories. However, when using robocopy, it can be frustrating if it encounters an error and continues to copy files despite the issue. This guide will help you understand why this happens and provide two methods to abort robocopy on the first error it sees.

In your case, you want robocopy to stop copying files as soon as it encounters a locked file or any other error. This is similar to the behavior of the xcopy /dry command. By following these steps, you can ensure that robocopy aborts the copy process on the first error and does not continue trying to copy files.

🛑 Root Causes of the Error

  • The primary reason why robocopy continues to copy files despite an error is because of the way it handles file operations. When the /R flag is set to 0, which means 'replace', robocopy only checks if a file already exists on the destination before copying it. However, this does not apply to the entire copy process, but rather to individual files. As a result, if one file fails, subsequent files are still copied.
  • Another possible reason for this behavior is due to the way Windows handles file locks. When a file is locked by another process or program, Windows will not allow it to be modified until the lock is released. Robocopy may continue to attempt to copy the file even after the lock has been acquired, resulting in an error.

✅ Best Solutions to Fix It

Using the /mov flag with the /nobatch option

  1. Step 1: Open a Command Prompt as administrator and navigate to the directory where you want to run robocopy. Type the following command: `robocopy /mov /nobatch source destination`.
  2. Step 2: The /mov flag tells robocopy to move files instead of copying them, which will stop the copy process on the first error.
  3. Step 3: The /nobatch option prevents robocopy from running in batch mode, which means it will not continue to copy files even if one file fails.

Using the /minage flag with the /nobatch option

  1. Step 1: Open a Command Prompt as administrator and navigate to the directory where you want to run robocopy. Type the following command: `robocopy /minage /nobatch source destination`.
  2. Step 2: The /minage flag tells robocopy to check for file age instead of checking if a file already exists on the destination. This will stop the copy process on the first error, even if it's due to a locked file.

✨ Wrapping Up

To summarize, you can abort robocopy on the first error by using either the /mov flag with the /nobatch option or the /minage flag with the /nobatch option. Both methods will stop the copy process as soon as an error occurs, ensuring that locked files are not copied and the entire copy process is halted.
