FTP, which stands for File Transfer Protocol, is the computer protocol that is usually used when transferring files to and from a server.

Accounts with a hosting plan may use an FTP program, such as FileZilla, to connect to the store's hosting server and move files to and retrieve files the server.

SFTP, or Secure File Transfer Protocol, is a more secure protocol for transferring files to and from a server. PCI Compliance rules prohibit FTP access, so SFTP is used instead.
