Hi Satish,
The Cloudshare External Address is only to your "SAP HANA Developer Desktop x64".
If you want to upload/share your local files to this Desktop-environment, you can do it via your Remote Desktop Connection to this external address.
If you want to ftp-files directly, I did use FileZila, you need to find the info via SQL command (SQL Editor --> select * from SYSTEM.FTP_SERVER).
I hope this will help you.
Regards,
Andre
