SFTP is an amazing protocol. I've been using it for a good 7 or 8 years now and it's been one of the most useful tools I have ever used.
SFTP features commands like get and put.
Well ZPE 1.8.7 added the send> command to the ZPEClient which allows sending a file to a ZENServer. Prior to this, I had been ensuring that all data between the client and server is secured using my own encryption system. Well, without hesitation, I knew that this had to come to file transfer too. So now ZPE can send and receive files that are encrypted and decrypted within the client and server. This breakthrough is a compelling reason to use ZPE since it offers a very strong alternative to SFTP.
Further to this, to make it even more powerful the client now offers the ls (list files locally) command and the rls (remotely list files) commands.
