Using the G Suite Admin console's file transfer ownership tool is the most efficient and streamlined approach for transferring file ownership. This tool is specifically designed to handle ownership transfers in bulk, ensuring that all files are transferred correctly without the need for manual intervention.
By utilizing this feature, you can transfer ownership of multiple files at once, rather than having to manually move each individual file, which can be time-consuming and prone to errors. The Admin console also maintains the shared settings and permissions, making it easier for the new owner to manage the files without disruption to their accessibility for other users.
This method not only saves time but also minimizes the risk of losing important files during a manual transfer process. Additionally, the other options, while potentially helpful in certain contexts, do not address the ownership transfer as effectively as the tool provided in the Admin console.
