FTP (File Transfer Protocol) is a protocol for transferring files between a computer and a server over a network. It uses the TCP protocol from the TCP/IP suite and can be used independently of the operating system (it is platform-independent). It was defined in 1985 in RFC 959 and extended in 1997 in RFC 2228. Its support is included in web browsers or specialized programs. That's the basics.
FTP is fundamental to hosting; without the FTP protocol, you cannot upload a website to hosting. The usual practice is to use an FTP client and save the FTP access data in it. Many years ago, a virus was found on the internet that could extract access credentials from Total Commander and FileZilla and attack hosting accounts. Since then, many people have stopped saving their data in FTP clients and instead re-enter it each time they connect. The simplest form of FTP access is the simplified notation, which is as old as the protocol itself.
ftp://login:password@hostitel Example: ftp://mydomain:This email address is being protected from spambots. You need JavaScript enabled to view it.
The simplified notation can be entered into any browser or, for example, into Total Commander by clicking on the URL icon. Simplicity is beauty.
