The error 'Cannot find Robocopy error in log file' occurs when the robocopy command fails to identify an error in its log file, making it difficult to determine which folder is causing the issue. This problem affects users who are running robocopy commands on Windows 10 64-bit (French version) and need to troubleshoot errors in their scripts.

This issue can be frustrating because it prevents users from identifying the specific folder that is failing, making it challenging to take corrective action. However, by following the steps outlined below, you should be able to track down the error and resolve the issue.

⚠️ Common Causes

  • The primary reason for this error is that robocopy is not correctly parsing its log file to identify errors. This can occur due to various reasons such as incorrect switch usage or insufficient logging options.
  • Alternatively, the issue might be caused by a problem with the Windows environment or the system's configuration, which affects the way robocopy logs and processes errors.

🛠️ Step-by-Step Verified Fixes

Use verbose logging to gather more information

  1. Step 1: Open the Command Prompt as an administrator and run the following command: robocopy /LOG:C:\path\to\logfile.log /V /S /E /DCOPY:DA /COPY:DAT /PURGE /MIR /XJF /XJD /R:0 /W:0
  2. Step 2: This will create a log file with detailed information about the command execution, including any errors that occurred.
  3. Step 3: Examine the log file to identify potential issues or discrepancies in the output.

Use robocopy's built-in error handling and filtering

  1. Step 1: Modify your robocopy command to include additional switches, such as /L (list) or /F (filter), to help identify errors more effectively.
  2. Step 2: For example, you can use the following command: robocopy /LOG:C:\path\to\logfile.log /V /S /E /DCOPY:DA /COPY:DAT /PURGE /MIR /XJF /XJD /R:0 /W:0 /L 100
  3. Step 3: This will display a limited number of files (in this case, 100) and help you identify potential errors or discrepancies in the output.
