Using FileZilla Software

Here is an overview of how to use the FileZilla software:

Connecting FileZilla to an FTP Server

Using Quick Connect

To connect to an FTP server, use the Quick Connect bar by entering details such as Host, User name, Password, and Port. For special servers like SFTP, prefix the address with the protocol (e.g., ‘SFTP://’). Enter the server’s port into the Port field if you’re not using the default port (21 for FTP and 22 for SFTP). After entering the information, press Enter or the Quick Connect button to establish the connection.

Using Site Manager

Site Manager is a tool that helps store and manage FTP login information. It provides more detailed information storage and configuration than Quick Connect. Use Site Manager to optimize the process of managing FTP accounts.

Special Case: Servers in LAN

If your server is located in a LAN, use the internal IP address of the host computer. For PC machines like FileZilla, you can use localhost or as the hostname for convenient connection.

Navigating on the FTP Server

After a successful connection, the data on the host will be displayed on the right side of the control panel. The folder name appears above, and the folder tree of the host appears below. To access a folder:

  • Type the folder name in the Remote Site box and press Enter.
  • You can select and open a folder in the folder tree by double-clicking or clicking on it.

Navigating on Your Computer

Once you have successfully connected to an FTP server, navigating on your computer becomes an important part of the FileZilla experience. The directories on your computer and the local folder tree are displayed on the left side of the workspace.

In this pane, you can view the size of the folder, view file and folder names, and quickly determine the location of important files and folders. This makes it easy for you to navigate through parts of your personal computer and select necessary content to transfer to or download from the server.

Synchronize Browsing

Use the synchronize browsing feature when you have a similar folder structure on both your computer and the server. This feature automatically mirrors any changes to the folder structure on both your personal computer and the server. To activate this feature, you can follow these steps:

  • Go to Site Manager > Advanced Tab, make sure that the local and remote folders have the same structure, tick the Use synchronized browsing option, then press Connect.

Compare Directories

Select View > Directory Comparison, choose to Compare filesize or Compare modification time, then select Enable to view the differences between the two directories.

Transfer Files

You can simply use the mouse, then hover over the file and right-click, then select Download or Upload.

Limit Concurrent Connections for Servers

If you encounter a 421 error message due to FTP server connection restrictions, you can follow these steps:

  • Create an entry for the server and enter the login details.
  • Tick the Limit number of simultaneous connections option.
  • Select the Maximum number of connections option to enter a connection limit.
  • Press Ok to finish.
