While CIFS and NFS are file system protocols, which means that whole file systems can be shared on the network, and other computers can use those file systems as if they were attached locally, FTP (File Transfer Protocol) is a TCP protocol for uploading and downloading files between computers. FTP works on a client/server model. The server component is called an FTP daemon. It continuously listens for FTP requests from remote clients. When a request is received, it manages the login and sets up the connection. For the duration of the session it executes any of commands sent by the FTP client.
Access to an FTP server can be managed in one of two ways:
In the Anonymous mode, remote clients can access the FTP server by using the default user account called “anonymous” or “ftp” and sending an email address as the password.
In the Authenticated mode a user must have an account and a password. User access to the FTP server directories and files is dependent on the permissions defined for the account used at login. As a general rule, the FTP daemon will hide the root directory of the FTP server, and provide access only to the FTP Home directory. This hides the rest of the file system from remote sessions.
Traditional FTP is rather insecure. When you login, your username and password are transmitted in clear text, raising the possibility of your credentials being 'sniffed' by a malicious person. Fortunately there's an easy answer to this. You can quite easily configure your FTP server to use OpenSSL encryption, so that username & password, and even data files, are encrypted during transfer.

Before deploying FTP on NAS4Free you should be familiar with:
Open a Terminal (Console, CLI) on your client PC and make sure you understand these commands:
You can also look them up on FreeBSD.org's Man Pages.
Or you may run it from the CDROM as required for testing.
See SUG Section 2.2-Using NAS4Free with the CDROM and a removable disk (LiveCD mode).
The following are basic commands you can use with a CLI to manage your FTP session. These commands should work on Windows and Linux clients.
For details about the FTP service please see SUG Section 6.2-FTP-File Transfer Protocol.
Connect your Client to the Network, and use PING to verify that you can reach the Server's IP Address. You can also try to open the NAS4Free WebGUI, if you are successful then you have a working connection.
Linux and Windows both have built-in, CLI based, FTP clients. Most people will probably prefer a GUI based client. A popular client is Filezilla, and Filezilla supports a version for most Operating Systems. There are many others and you can use Google to find one that's right for you.
The FTP service should now be running, so let's test the FTP Connection manually, with the CLI, before trying to use Filezilla. If you can't login, it's likely that there is no account created for you.
1 - Open a Terminal Window (Console, CLI).
2 - Type the following:
3 - Logon to FTP: If Anonymous Users was selected, your username will be anonymous, otherwise for local users, enter your username and press the “ENTER” key. Enter your Password and press the “ENTER” key. You should see something like this:
Connected to 192.168.1.250 220 ProFTPD 1.3.2e Server (ldknas4free FTP Server) [::ffff:192.168.1.250] Name (192.168.1.250:larry): ldk 331 Password required for ldk Password: 230-Welcome to NAS4Free FTP Server 230 User ldk logged in Remote system type is UNIX. Using binary mode to transfer files. ftp>
4 - Type the following:
5 - You should see the following:
ftp> ls200 PORT command successful 150 Opening ASCII mode data connection for file list drwxrwxrwx 3 root wheel 512 Jul 18 12:24 CF_Data_Part2 drwxrwxrwx 8 root wheel 7680 Jul 25 12:51 mysata drwxr-xr-x 4 root wheel 512 Jul 21 13:45 ramdisk1 drwxr-xr-x 3 root wheel 512 Jul 21 13:45 ramdisk2 226 Transfer complete ftp>
6 - Exit FTP:
This procedure just verified that you can connect manually using ftp. You will use the Menu's from Filezilla to transfer files.
REF: Basic FTP Commands
If you want to use NAS4Free behind a NAT box (router or firewall) that does not support FTP you should:
You will be opening several ports, these are generic instructions and it may be wise for you to consult the manufacturers' manual for information specific to your equipment and application. Port 21 may be blocked by some ISP's and therefore you may need to use another unassigned port, which probably would be a wise decision. For best results don't use known port numbers at all, use unassigned, private ports per IANA recommendations. If you have trouble configuring your router or getting it to work, look for help on the manufacturers' website or Google.
