FTP (File Transfer Protocol) is a standard network protocol used to transfer files from one host to another host over a TCP-based network, such as the Internet (Wikipedia).





For FTP programs to work properly you should check your network settings, the settings of firewall and antivirus software.

It is desirable to look into the error log. If the connection to the server was established, an error will be clearly described. If there is no connection then there is something wrong with the network or client settings. You may often need to use the passive mode, if your ISP sets limitations.

To establish an FTP connection you should observe the following conditions:

1. Your e-mail must be confirmed.
2. Your website must be at least 2 hours old (sometimes up to 24 hours) for FTP to work.
3. The installed security programs must not forbid FTP connection.
4. The passive mode must be selected.
5. Enter the data into your FTP client manually, and not by means of copy&paste.
