  • /XD *.tmp: Excludes files with the ".tmp" extension from the copy process.
  • /LOG:C:RobocopyLog.txt: Redirects the log output to a text file named "RobocopyLog.txt" in the C: directory.

3. Copying Files with Specific File Extensions:

robocopy C:SourceFolder D:DestinationFolder /S /XF *.txt *.log *.bak
  • /S: Copies subdirectories, but only those containing files.
  • /XF *.txt *.log *.bak: Excludes files with the ".txt", ".log", and ".bak" extensions from the copy process.

4. Resuming a Failed Transfer:

robocopy C:SourceFolder D:DestinationFolder /R:10 /W:30 /Z
  • /R:10: Retries failed file copies up to 10 times.
  • /W:30: Waits for 30 seconds between retries.
  • /Z: Copies files in restartable mode, enabling the transfer to resume after interruptions.

5. Verifying File Integrity After Copying:

robocopy C:SourceFolder D:DestinationFolder /MIR /V
  • /V: Verifies the copied files by comparing their contents with the source files.
