Move large files between network folders in ABAP

Hi, ABAP's experts.

I need to move a large file (100MB+) from one folder on the server to another.

After some search on SCN, I found the following ways to implement such task:

1. Use class CL_GUI_FRONTEND_SERVICES and its methods FILE_COPY( ) / FILE_DELETE( ).

2. Use commands OPEN DATASET, TRANSFER, DELETE DATASET and CLOSE DATASET.

I would like to know:

Which of these approaches is more suitable for the task?

Which of them is more preferable from performance point of view, we're talking about large files (100MB+)?

If you have any other ideas regarding to the task, please, feel free to share your opinion.

Thanks.
