No but you can install humyo SmartDrive which makes your online storage space appear as an additional drive on your computer. You can drag and drop files and whole folders to it.

You can also connect to your account using WebDAV. There are many WebDAV clients available, many of which operate just like an FTP client.

Since FTP is prone to problems with firewalled and NAT based Internet connections and neither FTP nor rsync have support for encrypted file transfers as standard, we do not and have no plans to support FTP or rsync access to your online storage space - WebDAV is the future!
