You can manage files on a Droplet using its Linux command line, which you can access by logging into your Droplet using SSH or the Droplet Console.
To connect to your Droplet through SSH, read How to Connect to Droplets with SSH. To connect to your Droplet through the browser using the Droplet Console, read How to Connect to Droplets with the Droplet Console.
Once you have connected to your Droplet, you can use the command line to navigate your Droplet’s file system. For more information about how to use the Linux command, see our Linux command line primer. If you need to transfer files to the Droplet, see our file transfer guide. If you want to add files to your Droplet, you would use SFTP which you can learn more about through our SFTP file management guide.
We do not provide any graphic user interface (GUI) system for Droplet file management. To use a GUI to manage a Ubuntu Droplet, you can install Ubuntu Desktop on your Droplet.
