FTP stands for File Transfer Protocol. Essentially, it is a simple tool to move files from one computer to another computer.
How would FTP work for me?
Lets assume that you have created a web site for yourself, and you have seventy-five web pages that you want to display to people. Instead of copying all of the files to disks and manually placing the files on the Web Server, you could open an FTP client, find the Web Server, navigate to the directory where you need to place the files, and then upload the files.
Thus, FTP is simply used:
to download a file from a server using the Internet, or
to upload a file to a server (e.g. uploading a web page file to a Server).
FTPS (also known as FTP Secure or FTP-SSL) is an extension to the commonly used File Transfer Protocol (FTP) that adds support for the Transport Layer Security (TLS) and the Secure Sockets Layer (SSL) cryptographic protocols.
FTPS works only on Port 21 for LogicBoxes's cPanel Linux Hosting, Plesk Windows Hosting, Single Domain Linux and Windows Hosting, Multi Domain Linux and Windows Hosting, Reseller Linux and Windows Hosting packages.
Some FTP clients support both FTPS modes: Explicit and Implicit. In such FTP clients, the Explicit (FTPES) mode needs to be selected.
