fix: enhance file copy logic for same device checks

- Updated the check in checkAndCopyFile to ensure that big file copy logic only triggers if the source and target are on the same device.
- Added a condition to verify device equality using FileUtils::isSameDevice before initiating the big file copy process.

This change improves the file copy operation by preventing unnecessary delays and ensuring that
the big file copy logic is only applied when copying files across different devices, enhancing
overall performance and reliability.
