File Transfer Protocol

File transfer protocol is a set of rules that computers follow for the transferring of files from one system to another over the Internet. It may be used by a business to transfer files. Or site developers may use FTP to upload or download files from a Website's Server.

What is FTP

FTP is an acronym that stands for File Transfer Protocol. This is a program that allows you to transfer files from one computer to another. Or for working on websites transferring from your device to a Web Server.

For example, if you created your web pages on your computer, either using a text editor or some other web page editor. You will then need to transfer those pages to your Website. We can accomplish this very easily with an FTP Client.

How Does FTP Work?

FTP (File Transfer Protocol) uses two separate TCP connections: a command channel (usually port 21) for sending instructions and receiving replies, and a data channel for transferring files. The client connects to the server, authenticates with username and password (or anonymously), then sends commands like LIST (view directory), RETR (download), or STOR (upload). For the actual data transfer, FTP offers active mode (server connects back to client from port 20) or the more common passive mode (client connects to a random high port the server opens), which works better with firewalls and NAT. Files transfer in ASCII mode for text or binary mode for everything else, with support for resuming interrupted transfers. Because all data including login credentials, travels unencrypted in standard FTP, secure alternatives like FTPS or SFTP are now the recommended choice.

What is SFTP

With an FTP program, a secure channel is not provided to transfer the files between the hosts to transfer or copies file from one host to another host or systems. It normally uses port 21 which is a non-secure port. It establishes the connection under a standard TCP protocol, in which it does not encrypt the data before sending.

SFTP Stands for Secure File Transfer Protocol. This protocol works the same as FTP but provides a Secure channel. SFTP establishes a controlled connection under SSH protocol, and it normally uses in port 22. SFTP encrypts data before sending files. It works on a Transparent FTP Tunneling Method for transferring of files. SFTP maintains full security of the data by using SSH keys.

What is Anonymous FTP

Another method for using the File Transfer Protocol (FTP). With anonymous FTP, you normally do not need to identify yourself before accessing files. In most cases, you enter the word anonymous or ftp when prompted you for a username. You can enter anything for the password, such as the word “guest”. In many cases, when you access an anonymous FTP site, you won’t even be prompted for any username and password.

FBI Warns About FTP Server Vulnerability. The warning focused on the file transfer protocol (FTP) and the Anonymous FTP, as it is called, does not require any authentication. A security researcher, Minxomat, after a quick scan found about 800,000 anonymous FTP services were exposed. And even the developers at cPanel Issue Warnings.

Types of FTP Protocols

FTP has evolved into secure variants to address its original lack of encryption:

  • Standard FTP: Unencrypted; fast but vulnerable to interception. Use only on trusted internal networks.
  • FTPS (FTP Secure): Adds SSL/TLS encryption to standard FTP. Supports explicit mode (upgrades from plain) and implicit mode (always encrypted). Retains FTP commands for compatibility.
  • SFTP (SSH File Transfer Protocol): A completely different protocol built on SSH (port 22). Encrypts everything in a single channel, supports key-based authentication, and offers better firewall compatibility.

FTP Folders

In FTP, folders (also called directories) organize files on the remote server just like they do on your local computer.

When you connect to an FTP server, you typically start in your home directory (the default folder assigned to your user account). From there, you can navigate, create, rename, or delete folders using simple commands.

In graphical clients like FileZilla, you browse folders the same way you would in Windows Explorer or Finder - just double-click to enter a folder or use the arrow buttons to go up.
In command-line FTP, use cd foldername to change into a directory, cd .. to go up one level, mkdir newfolder to create a new folder, and rmdir oldfolder to remove an empty folder (note: you cannot delete non-empty folders with rmdir in most FTP clients).

Understanding folder permissions is key: your account may have read/write access only to specific directories (such as public_html or www for web hosting), while other areas are restricted for security. Properly organizing your FTP folders - for example, keeping images in an images/ folder, scripts in scripts/, and backups in a separate backups/ directory - makes website management, file sharing, and maintenance much more efficient.

Logging in to FTP

You will need an FTP Client and your FTP login credentials (Contact support if you do not have FTP login credentials).

Connecting via FTP

To connect to your website with FTP, you will need to input the required information as list below

Profile Name
This is just a reference name for your website.

Host Name or Address
The name of the Server you will be connecting to. Usually this will be your Domain Name. But could also be IP numbers.

Username
The username for your FTP account

Password
The FTP password created for you during sign up

Using Your FTP Client

This is general information for any FTP client. Yours may be slightly different, but all normally need the same info to work properly.

Start your FTP client. You will see several boxes that will need to be filled out.

The first is normally the Profile Name. This is simply a label to give to this particular website.

Next box is the Host Name or Address. This is normally your Domain Name or IP numbers of your website. If you are not sure, ask your Hosting Provider. It will look something like this: [ftp.domain-name.com] Or just [domain-name.com]

The other information are your User ID and Passwords. These are again normally the same as the user-name and password that you gave when you signed up for the hosting service.

You may want to click on the button that saves your password, so you will not have to type it every time.

Once you have your settings filled out, click Connect or OK. You will know this is complete when files from your Website show up on the right side of the screen.

You may want to set up the folders on your Web Hosting service exactly the same as you set them up on your computer, so you will always remember to send your files to the correct folders.

Transferring Files

The left side of the screen are the files on your computer. Find the file that you want to transfer by double-clicking on the folders until you get to your file.

The right side of the screen are the files on your Website. Go to the folder you want to transfer your files to.

You can either double-click on the file you are transferring, you can Right-Click - Upload-File, or single click on it and then click on the arrow that points to the right side of the screen. Which ever way, you will now have a file on your hosting server.

To move a file from the Web Server to your computer, do the same thing except click on the arrow that points to the left side of the screen or Right-Click -Download-File.

You can also view, rename, delete and move your files around. If you need to create a new folder for your files, you can do that too by clicking on MkDir or Right-Click - New-Directory.

Most all FTP Clients have a built-in Text editor where you can edit your files or web pages by hand.

Using Windows Command Line FTP

To use the built-in FTP client on Windows:

  • Open Command Prompt
  • Type: ftp ftp.example.com (or just ftp for interactive mode)

At the ftp> prompt, log in:

user yourusername
[enter password]

or for anonymous access:

anonymous

Common commands:

  • dir - list files
  • cd folder - change remote directory
  • get filename - download file
  • put filename - upload file
  • binary - use binary mode (recommended)
  • quit - exit

Important: Windows FTP uses active mode by default and often fails behind firewalls/NAT.
For reliable transfers, use FileZilla or WinSCP instead.
Standard FTP is unencrypted, use only on trusted networks.
