The correct answer is File transfer.To move a copy of the file from one computer to another over a communication channel is known as File transfer.The File Transfer Protocol (FTP) is a standard communication protocol used for the transfer of computer files from a server to a client on a computer network.FTP is built on a client-server model architecture using separate control and data connections between the client and the server.FTP users may authenticate themselves with a clear-text sign-in protocol, normally in the form of a username and password, but can connect anonymously if the server is configured to allow it.For secure transmission that protects the username and password, and encrypts the content, FTP is often secured with SSL/TLS (FTPS) or replaced with SSH File Transfer Protocol (SFTP).Additional InformationHow to encrypt a file?File encryption helps protect your data by encrypting it.Only someone with the right encryption key (such as a password) can decrypt it.File encryption is not available in Windows 10 Home.Right-click (or press and hold) a file or folder and select Properties.Select the Advanced button and select the Encrypt contents to secure the data check box.Select OK to close the Advanced Attributes window, select Apply, and then select OK.File CopyingIn digital file management, file copying is the creation of a new file that has the same content as an existing file.Computer operating systems include file copying methods to users, with operating systems with graphical user interfaces (GUIs) often providing copy-and-paste or drag-and-drop methods of file copying.
