Under the Mac OS X system, there are many excellent FTP tools, such as Cyberduck, transmit. But do you know that in addition to these third-party applications, the system has prepared a built-in FTP tool for you.
Enter "Go-connect server ..." From the Finder menu bar (shortcut key CMD + K)
Enter FTP server address (such as: ftp://ftp.mozilla.org)
Click the + button on the right of the address bar to add the current address to your personal Favorites Server
Click on the "Connect" button and follow the prompts to authenticate successfully to connect to the FTP server
P.S. If you need to connect to an FTP server that supports SSL, you can modify the protocol prefix FTP for FTPS. Once the server connection succeeds, you can manipulate the remote FTP Server directory in the Finder as you would browse the local folder. Of course, the built-in FTP tool can only give you these simple operations, if you need more rich features or recommended by the introduction of the Third-party FTP application.
Because Mac os X is a unix-based operating system, for friends who are familiar with command-line mode, you can type in a terminal (Terminal) Application: FTP enters FTP mode for operation.
