Here are a number of the more popular tools you'll find on LC systems for moving data between different destinations.
Hopper is a powerful interactive tool that allows users to graphically move, copy, find, delete, and otherwise operate on files. Users can connect to and manipulate resources using ftp, ssh, sftp, htar, Endeavor (nft), and other protocols.
FTP (File Transfer Protocol) is an industry-standard protocol and user interface for transferring files between computer systems by means of a series of interactive commands. FTP involves a local client (software you execute to send or receive files) and a remote server (software elsewhere that responds to instructions from your client to accept or deliver files).
