Hello Catmaniac,
Sorry to hear that you're trying to transfer your hosting to 1 and 1. We, unfortunately, cannot help you with the transfer to 1 and 1, but you should discuss how to move your files with 1 and 1's support team. We typically recommend that you use FTP. If your site uses a database, you will need to export the database. If you're trying to move a domain name that is registered through our services, then you will need to contact our Customer Service team for further assistance. You can find their contact information in this link (Contact Us).
If you have any further questions or comments, please let us know.
