Using SFTP Client

SFTP is a secure file transfer protocol. It's based on SSH (Secure Shell) protocol used to access remote server's Terminal over the network. Because of this, it's very secure and super fast! It's replacing FTP (File Transfer Protocol) and FTPS (File Transfer Protocol Secure) more by every day.
FreeMC.Host servers can all be accessed from SFTP. But to make use of this, we need to get SFTP Client first!

FileZilla

FileZilla is the most popular free FTP and SFTP Client. It is supported on Windows, macOS as well as Linux platforms.
From my experience, it is the fastest FTP/SFTP client there is. It also is known to handle slow connections very well, wherein the case of other Clients they would fail transfer. Because of this, I highly recommend using FileZilla!

Installing

Let's start by downloading from https://filezilla-project.org/download.php?type=client.

And going through the standard installation procedure.

Now FileZilla will open.

Connecting

Click on the Sites manager button, the first button on the toolbar. Create a New site and name it. Change Protocol to SFTP - SSH File Transfer Protocol.

Now go to the Panel and click on your Server's Name to open Console.
From there, expand Configuration and go to SFTP Settings page.
Copy Host from Connection Address as shown on the Screenshot below and Paste into FileZilla.
In Port input 2022.
Copy Username from the Panel to the FileZilla as well.
Input your Panel account password. If you don't know your Panel's password you can change it on this page.

Now click Connect!

Tick the box to Always trust host and confirm with OK.

Interface

Let's take a look at FileZilla's interface.

You can also double-click on files from Local Computer's window inside FileZilla to upload into Current directory of the server.

Manipulating files/folders

Right-clicking on any file/folder or space will open the context menu from where you can Create new Files and Directories, Rename file/folder or delete them.

Moving files and folders is also very simple. Just drag & drop them into a new directory (you can also drop them into Tree view).

When you do this for the first time, you will be prompted if you want to use your default text editor or choose another one.
