FTP
The File transfer protocol (FTP) is a language that computers speak for transferring files from one computer to another over the internet.
It can be used to transfer images, videos, WordPress core files and anything else files from one server system to another. It’s also often used to maintain websites and to edit, upload and download files on a web server.
FTP credentials always contain:
– Hostname
– Port (Default 21)
– Username
– Password
They are provided by the hosting provider or within the hosting dashboard.
