In FTP file transfers, all text, HTML and script files must be transferred in ASCII-mode, and all executables, images and zip files, etc., must be transferred in BINARY-mode. By default, 3D-FTP uses an Auto-mode, where it uses this list to determine which mode to use. This list contains all filename extensions (or filename masks) that need to be transferred in ASCII-mode, and files NOT matching any criteria in the list are transferred in BINARY-mode.
Keep Alive
Keep Alive Commands and Delay
FTP Servers are normally configured so that they disconnect all idle (=non-active) clients after a certain idle period (like 60 seconds or 5 minutes). 3D-FTP fools these servers with its Keep Alive feature by sending a dummy command every 60th second (this is user configurable), effectively making the Client look active. You can change the set of the commands (separated with semicolon) that are sent to the server. You can also change the delay between each command.
Reconnect automatically
Some servers cannot be fooled by Keep Alive-commands, but they disconnect all clients that have not made an actual file transfer within idle-period. You cannot prevent these servers from disconnecting, but automatic reconnect feature commands 3D-FTP to reconnect to server if its been disconnected by server for any reason.
If auto-reconnect is turned off, you can select Reconnect-command from Site-menu (or press Ctrl-R hot key) to reconnect after being kicked out by server.
FTP Server LIST Command
By default, 3D-FTP sends a LIST command to the FTP Server to get the remote file listing. Some servers do not return a full list, but require some extra parameters to return the full listing. The most-used custom command is LIST -al. With this command, many servers return the full listing, including hidden files. These commands are non-standard, but you can safely start experimenting with the LIST-al command if your FTP Server does not display hidden files. You can get more information about custom commands from your FTP Server administrator.
