RANSFER SETTINGS

To access transfer settings 

1.  From the menu, choose Tools > Global Options. 

2. Select Transfer. 

Transfer method 

Choose Auto detect to have CuteFTP decide the transfer method based on the file 

and server type. 

Choose ASCII to transfer text files, web pages or other text type files. 

Choose Binary to transfer pictures, programs or executable files. 

Note: 

Binary files cannot be transferred in ASCII mode, but ASCII files can be 

transferred in Binary mode. 

Data mode: 

Choose Auto and CuteFTP  makes connections in PASV mode. If the PASV 

connection fails, CuteFTP attempts to connect in PORT mode automatically.  

PASV helps avoid conflicts with security systems.  PASV support is necessary for 

some firewalls and routers, because with PASV, the client opens the connection to 

an IP Address and port that the server supplies. 

Choose PORT when connections or transfer attempts fail in PASV mode, or when 

you receive data socket errors. When an FTP client connects using PORT, the server 

opens a connection to an IP Address and port that the client supplies. 

EPRT is an extesnion of PORT that allows the server to give an Ipv6 address to the 

client for negotiation through NAT firewalls. 

EPSV is an extesnion of PASV that allows the server to give an Ipv6 address to the 

client for negotiation through NAT firewalls. 

Used as an alternative to PASV or PORT commands for the traversal of NAT 

firewalls for secure (FTPS) connections. Read RFC 2428 for more details. Common 

 Add EPRT and EPSV to the existing Data mode drop down (combo) located under 

Global Options | Transfer pane. Note that each site in the site manager is currently
