What is SFTP? How to transfer files using SFTP?
FTP (File Transfer Protocol) is widely used to move large files over the Internet. SFTP (Secure File Transfer Protocol) on the other hand, is a more secure version of FTP that was developed to overcome some of FTP’s security weaknesses. SFTP encrypts logins, passwords, and files to avoid eavesdroppers from stealing sensitive information. This allows SFTP to be used on a server that is open to the public, so long as the user account has appropriate permissions. Back to Top
SFTP is a file transfer protocol intended to replace the outdated FTP protocol. SFTP, or Secure File Transfer Protocol, is a protocol that encrypts your data between your computer and your server. It is often used on FTP servers to allow you to upload, download, and manage files without having to use FTP. The SFTP protocol is available for the Windows and Mac operating system.
SFTP, also known as SSH file transfer protocol, is a secure file transfer protocol similar to FTP, but more secure because files are transferred over an encrypted SSH connection.
So while you get all the functionality of FTP, you also get the security of SSH. In this article we will see what SFTP is and how you can use it to transfer files.

As mentioned above, SFTP is simply a file transfer protocol that works over an encrypted SSH connection. Unlike SCP, SFTP allows you to do much more than just transfer files. The protocol also allows for a lot of manipulation with directories and files.
Since SFTP is an SSH subsystem, it also supports all SSH authentication mechanisms. To open a connection to a remote system, use the command sftp followed by the username and IP address of the remote server, just as you would to establish an SSH connection.
sftp [email protected]_IP_address
If the host is password authenticated, you will also be prompted to enter a password. Once the connection is established, an SFTP prompt appears. Here you can start entering commands and interacting with the remote server.

Downloading files via SFTP
Use the get command to download files from the SFTP server.
Get the file name
You can upload multiple files at once by listing them one by one.
get file1.zip file2.zip file3.txt
To load directories, use the -r flag to execute the recursive directory.
get -r directory1
If the download fails or is interrupted, you can continue it with the command reget.
Uploading files to SFTP server
To upload files using SFTP, we use the put command.
By default, put downloads files from your current working directory. If the file you want to download is not in the directory from which you start the terminal, you must specify the absolute path to the file you want to download.
The same flags and options apply to the put command as to the get command. A z. B. To load a directory, use the following command.
put -r directory1
Or resume a failed or interrupted download.

Frequently Asked Questions
What is SFTP and how does it work?
SFTP is a protocol for transferring files between a client and server over a network. The most common use of SFTP is to remotely transfer files from the server to the client. Because the files are transferred across the network, the client could be just about anywhere, including across the globe or in a different country. Another common use of SFTP is to access files on a server. As a result, many of the most popular SFTP clients are used to access files on servers hosted by a host, or web host, or web host provider. Secure File Transfer Protocol, or SFTP, is a network protocol that allows you to transfer files between your computer and a remote host. It’s different from the more common File Transfer Protocol (FTP), which sends a file in clear text. That means that even if you’re using an encrypted protocol such as HTTPS, any information about or messages sent to your computer can still be intercepted, which is why SFTP is so popular with gamers. A script is a set of instructions that gives your computer a command to follow.
What is SFTP process?
FTP, or File Transfer Protocol, is an incredibly common file transfer protocol that allows you to upload and download data from a server to your computer over the internet. It is used by everyone from small business owners to individual users looking to backup files. The problem is that it is not a secure protocol, so the data you send over FTP is not encrypted, and is vulnerable to sniffing by other users or applications. SFTP is a process in which files are transferred from one machine to the other over a secure data channel. The process uses SSH to create a secure connection where both the sender and the receiver can share files and edit them from their end. SSH is a system of encrypting messages or files and using a key to decrypt those messages or files.
How do I transfer files using SFTP in Windows?
Ordinarily, file transfers are a pretty straightforward affair, with both parties on the same page. That’s not the case, however, when you’re using SFTP (Secure File Transfer Protocol), which is designed for use with a Web server. SFTP is a great solution for transferring files securely, but it adds a layer of complexity to things. File transfer protocol, also known as FTP, is most commonly used to transfer files between a server and a personal computer. The person setting up the server (the admin) can configure it so that FTP users have rights to upload, download, and delete files and create new folders. The server user can also give out an FTP address to anyone who wishes to transfer files to the server.
