FTP, FTP/S, and SFTP are common acronyms, but did you know that there are some significant differences among them? Notably, FTP in its basic form is not secure. FTP/S takes the security up a step in that it allows you to secure all or part of a session (at the cost of speed). SFTP is a completely different protocol (in spite of the similar acronym) that is natively secure and more efficient.
FTP (File Transfer Protocol)
FTP is a very well-established protocol, developed in the 1970s to allow two computers to transfer data over the internet. One computer acts as the server to store information and the other acts as the client to send or request files from the server. The FTP protocol typically uses port 21 as its main means of communication. An FTP server will listen for client connections on port 21.
FTP clients will then connect to the FTP server on port 21 and initiate a conversation. This main connection is called the Control Connection or Command Connection. The FTP client will usually authenticate itself with the FTP server by sending over a username and a password. After authentication, the client and server will typically, through a series of synchronized commands controlled by the Command Connection, negotiate a new common port called the Data Connection over which the file will be transferred. The Control Connection remains idle until the end of this exchange, when it reports that the file transfer has either failed or was completed successfully. The conversation between client and server is performed in plain text—all communication between the two parties is sent unprotected, verbatim, over the internet. This makes FTP very unsecure; it would not be terribly difficult for a third party, such as a Man-in-the-Middle Attacker (MITMA), to steal users' credentials.
- Overview of FTP and sftp clients. FTP client sftp client. FTP and sftp are two different types of clients that provide a form of file transfer. FTP (File Transfer Protocol) is the standard protocol for transferring files to and from remote machines running FTP servers.
- WinFTP Pro – a multifunctional FTP, SFTP, WebDAV, Amazon S3 and SCP client for Windows 10. WinFTP Pro provide secure file transfers between a local and a remote computer by utilizing the Secure Shell (SSH) technology. It also supports the SCP and SFTP protocol. WinFTP Pro also provides basic file management and synchronization functionality.
- FileZilla is one of the most popular desktop FTP clients, and the product is easy to configure to transfer files via the SFTP server you just set up. Setup for other FTP clients like Cyberduck, Transit, and others should be similar. Here are the steps to take to connect FileZilla to your SFTP server: Open FileZilla and navigate to File Site.
- Transfer files with FTP, FTPS, SFTP and Cloud Services (Including SSH Terminal).
There's an exception to this rule called One Time Password (OTP), in which the server sends a series of digits to the client server in response to the receipt of the USER command. The client grabs those digits and, using a pre-known algorithm such as ROT13 or MD5, the client will generate a hash of their password along with the series of digits to produce a unique password (used one time, hence the OTP). The client presents this hash to the server, which takes the user's password, already stored on the server, and uses the same digits. If the hashes of the password match, they are authenticated. This is somewhat more secure because the user's password does not go over the wire– only a hash of the user's password– so a MITMA usually can't reverse engineer the password from the hash.
The need for a Data Connection, and its inherent security loopholes, is a major concern in internet usage today. FTP traditionally requires a block of ports to remain open on either the server firewall or the client firewall to aid with the creation of Data Connections. For security reasons, companies are limiting the number of ports in their publicly facing firewalls and looking for alternate solutions in order to keep ports closed and information secure.
Welcome to the homepage of FileZilla®, the free FTP solution. The FileZilla Client not only supports FTP, but also FTP over TLS (FTPS) and SFTP. It is open source software distributed free of charge under the terms of the GNU General Public License.
FTP/S (File Transfer Protocol over Secure Sockets Layers)
Along with file transfers, clients will typically request directory information from the FTP server. The format of information in directories is often primitive by today's standards, and as such, the FTP client is sometimes only able to retrieve a subset of the attributes or properties of files available on the server (for instance, the date the file was last modified, but not the date of the file's creation).
While generic FTP is not secure, extensions have been added over the years to allow for the securing of FTP conversations—namely, the industry standard 2048 bit Transport Layer Security (TLS), the most upgraded version of the old 1024 bit standard SSL. FTP over SSL (FTP/S, as it's commonly known) allows for the encryption of both the Control and Data Connections either concurrently or independently. This is important because the negotiation of the SSL connection is time-consuming, and having to do it twice—once for the Data Connection and once for the Control Connection—can be expensive if a client plans to transfer a large number of small files.
FTP/S commonly runs on port 990 and sometimes on port 21, the primary difference being that port 990 is an Implicit FTP/S, and port 21 is an Explicit FTP/S. If a client connects to an FTP/S server on port 990, the assumption is that the client intends to perform SSL. Therefore, the SSL handshake takes place immediately; it is referred to as Implicit because the port number implies security. FTP clients who connect on port 21 and intend to use SSL for security will need to take the extra step to explicitly state their intentions by sending an AUTH SSL or AUTH TLS command to the server. Once the server receives this command, the two parties perform an SSL handshake and enter a secure state—hence why port 21 is referred to as Explicit. This allows the client the opportunity to activate greater security when necessary, or speed the process up on less security-sensitive file transfers.
SFTP (Secure File Transfer Protocol)
SFTP (Secure File Transfer Protocol) is a relatively new protocol developed in the 1990s, which allows for the transfer of files and other data over a connection that has previously been secured using the Secure Shell (SSH) protocol. While similar to FTP/S in that both protocols communicate over a secure connection, that's basically where the similarities end.
Unlike FTP, the SFTP protocol is packet-based instead of text-based. Where FTP might send a command such as 'DELE file.txt,' SFTP would send a binary 0xBC and then 'file.txt.' The key difference is that by sending less data, the SFTP protocol is faster over the long-term as less data is crossing the wire.
Another difference is that with SFTP, file transfers are performed in-line over the main Control Connection, thus eliminating the need to open a separate Data Connection for transfers. This has many benefits. First, by re-using the main connection, no other connections are opened between the client and the server, resulting in a single secure, efficient connection through firewalls.
Since SFTP runs over SSH, it is inherently secure. There is no non-secure version—the encryption cannot be triggered or turned off using AUTH commands, as in FTP/S. This is a plus for system administrators who are trying to enforce corporate security policies.
Another difference is that most versions of SFTP Server software are able to deliver a much richer and more detailed set of data about the files, such as the permissions, date, time, size, and other information not normally available to FTP, thanks to the more robust request protocol of the SFTP.
These are the inherent differences between FTP vs SFTP and FTP/S. Titan FTP Server Enterprise Edition supports both FTP and SFTP.

Maybe you've used an FTP or SFTP client before or maybe you're looking for one which should meet all your needs. We've reviewed many of them and picked the top ten FTP client you can use on Windows computer, and few more when you're seeking for more alternatives.
When it comes to access or edit files on your server, maybe you need to access or manage your WordPress website's files, and with an FTP client, the process is straightforward and very simple. An FTP client comes handy when you have to deal with your server, your hosting server or manage your cloud storage account, a good FTP client can save your time. Fortunately, these days finding alternatives is easier and a google search away. But we've not mentioned the overrated (not always) client like FileZilla etc. Instead, we tested those who are living under the rock and ready breath on your computer.
Free FTP/SFTP Client
1. CyberDuck
The advanced, free and with lot's of features —Cyberduck is our favorite FTP client, psst! It also supports SFTP, Amazon, WebDav and around 10 more connections including Google Drive and Dropbox. You get all the unusual and pretty much everything you ever want with an FTP/SFTP client. This website runs on cloud hosting powered by DigitalOcean, and from the Day I used this client, I never looked for any alternative, and there is no reason to dump it and use another FTP client. But that depends on person to person. Talking about features, it has all those basic and even more like editing files using your favorite Text Editor (Notepad or Notepad++) and changing file permissions. It is available for MAC and Windows operating system.
Note: The only problem I faced was when I slowly double click on a folder to rename it, and it may sometimes consider this a folder opening action that causes the program to crash.
2. SmartFTP
At first glance, it would seem that you are using a file explorer of Windows 10. But in reality, it is a very good Ftp Client that supports multi-windows, history, and sort of other necessary and even useless. So many buttons may annoy you, and from my perspective, it's probably not a user-friendly client. It comes with a 30-day free trial. With a very familiar look (as the interface is like once we see on Windows Explorer) makes the possibility that working on it would be easier. Along with many connection types, it supports SFTP, Telnet, ssh and storage like onedrive and Google Drive.
Free Ftp Clients For Windows
Talking of Interface and the features it gives the best of them while it might be little overwhelming for a new user (like me) to play with all those buttons it does have.
3. sFTPClient
It's a less powerful FTP and sFTP client that run on Chrome (extension) and native application are available for Windows, Linux and MAC OS. I didn't try its native applications for Windows, but I installed the Chrome extension that is around 3MB in size. You can simply enter your SMTP details and access your server files right from your Chrome web browser. There will be all simple and necessary actions and features. Hopefully, if you do like Google Chrome extensions, this is recommended sFTP client
Install / chrome extension
4. CarotDAV
It looks like this simple WebDAV supports even the older operating system from Windows 2000 to Windows 10. It also supports FTP, Amazon, and tons of other file storage services. The interface will remind you those Windows XP icons and along with lightweight installer it comes will all basic features, such as Edit, move, copy, rename, etc. CarotDAV is super lightweight and also comes in a portable version which is less than 2 MB, but that doesn't mean it has all the features.
5. WinSCP Lightweight FTP/SFTP client
Another lightweight/standalone FTP or SFTP client for Windows and can share site setting with the Putty (A ssh client). It provides a graphical interface to deal with files and folder on a server and has similar interface (if compare to SmartFTP) but a lighter solution for those looking for an easy way.
Install (Various OS)
6. Coffeecup Free FTP
It is a hell combination of simplicity and features, the program supports windows 10/8 and 7. A user friendly interface that will not take any longer to get used to it. The Pro version comes with built-in HTML editor that makes writing code directly to your server files super easy. It also comes with a bookmarking feature that you can use to pin directory or service and access them quickly for the next time. Most of the features are available in the free version of the software, and the Pro plan comes with code completion features that we talked earlier in the beginning.
It is basically a multi-window interface that makes possible to view your computer files and your server files at the same time and transfer files between them. There will also be a terminal feature that may help you deal with SSH based servers, so if you want one client that supports multiple FTP/sFTP connections and SSH terminal, this can be a game changer for you and save a lot of your time. It also has some shortcut button, for example, the 'Archive' button can create a backup of files and store them in a ZIP or RAR format, a nifty way to backup your site data or servers.
Install (various OS)
7. Transmit (for MAC)
The team recently launched the transmit 4 that comes with a brand new look and tons of new features. It supports file transfer from one server to another, so if you are dealing with more than one server it comes really handy. It can also send SSH commands that again make it even powerful (sorry Putty). Having a twin-turbo engine makes transferring smaller files ultra-fast maybe that's what you need, and also support multi-connection helps doing things quickly and faster. As for now transmit only support Mac OS operating system, umm bad news for windows users.
Install (Mac)
8. FTP Face
Ultimately open source FTP client hosted over SourceForge and supported multiple operating systems. It comes with built-in tools to play audio and view images, or even you can GZIP compress in one click. Directv login watch. While it is a lightweight gtk+ based FTP client that doesn't mean it could not provide advanced features like multi-window interface and task manager. Again it supports FTP commands directly from the interface without digging into anything.

9. And FTP
Smartphones are taking place all over the world, and now they are capable of doing great and amazing kinds of stuff. FTP client are not limited to computer operating system, so it's we will nice if you can access your FTP server on your Android phone and on-the go, anywhere and anytime. And FTP is a mobile app that can do exact same operations you could do on a real computer.
Install (android)
10. FireFTP
Finally a Firefox addon to bring the ability to access any FTP server inside the Firefox browser. For sure Firefox browser supports various operating system that also means you can install this add-on multiple operating systems. You will need a Firefox browser to use this FTP client. You might know that Firefox officially offers a total of five extensions but recently due to a quit they're retiring four of the extension, and they won't be able to install from the next year and same month.
Install (Firefox Browser)
11. Web Based Clients
Unlike setup based programs these client are web-based so there is no need to install anything on your computer. With just a web browser, you can access your Ftp account on the go and manage or start editing files right from your browser. Below are some web-based ftp clients is mentioned.
- http://www.net2ftp.com: No sign-up is required and connect to your FTP or any account easily in a matter of seconds. Few more web based FTP/other client.
- https://app.anyclient.com : All the connection are thought SSL encryption which makes it a safe online client that only need a account to get started. It's a web-based tool so ensure you're using a latest and top rated Web Browser like Google Chrome for more security.
Perhaps the best, and fast FTP client is CyberDuck that actually supports many other connections such as SFTP (ssh based FTP), or even some Cloud Storage accounts. Its simplicity and usability makes it stand out from the competitors. If you're looking for alternatives you can check CarotDAV, that is even more simpler and does the job all the time. The once mentioned on this page are more suitable for establishing an FTP or SFTP connection, and there are more powerful client are available if you're just looking for a Google Drive client (like Insync). Also, when you're dealing with an SSH based FTP server and when you're master with commands Putty comes handy as it is lightweight and click to open tool available for Windows. But as it is solely based on coding, you may want to dump and use
There are more niche specific client out there, if you feel something is missing in this article, we'd love to talk about it.
Personal Note: I was trying to install WordPress on DigitalOcean Server, but by default they lock the WordPress setup behind a password that can be changed or removed using a SSH client like Putty, I wish there was something easier to do it, so I took help from ServerPilot to create a server and install WordPress on it, and hopefully after than accessing the server using a SFTP client 'CyberDuck' made it easy to manage the site's file directly. Some hosting comes with built-in FTP managers but they always not meet your expectations.
