VirtualBox offers several ways to attach VMs to the network and uses
NAT by default, which mostly isolates them and makes them unsuitable
for use as servers or for shared files. You'll want to pick a
different way of attaching the VM to the network. This page does a
nice job of describing them so you can decide which is best for you:

Two sftp servers that are popular and quick to set up are
openssh-server and vsftpd, both of which are in the Ubuntu
repositories. Each will run automatically when the VM is launched and
each can be connected to with a variety of methods (PuTTY, FileZilla,
browser, command line, etc.) at the VM's IP address with the
credentials of the VM's users.

Below are basic instructions for each of them, but you should also do
your own research to familiarize yourself with their details to make
sure you're protecting your data and access to the server(s)
properly, etc.

To install and set up openssh-server in a VM:

	1) Open a terminal window in the VM.

	2) Install the server with this command:

	sudo apt install openssh-server

	3) Back up the config file with this command:

	sudo cp /etc/ssh/sshd_config /etc/ssh/sshd_config.original

	4) Edit the config file with administrative rights with this
	command:

	sudo nano /etc/ssh/sshd_config

	5) Make the changes you'd like inside the config file,
	opening the sshd_config man page in another terminal window
	to use as a reference.

	6) Save the file by pressing the Ctrl and o keys at the same
	time, then pressing the Enter key, then pressing the Ctrl and
	x keys at the same time.

	7) Restart the server with this command to make the changes
	take effect:

	sudo /etc/init.d/ssh restart

	8) Close the terminal window(s).

To install and set up vsftpd server in a VM:

	1) Open a terminal window.

	2) Install the server with this command:

	sudo apt install vsftpd

	3) Back up the config file with this command:

	sudo cp /etc/vsftpd.conf /etc/vsftpd.conf.original

	4) Edit the config file with administrative rights with this
	command:

	sudo nano /etc/vsftpd.conf

	5) Make the changes you'd like inside the config file after
	reading the descriptions for each setting in the file and
	opening the vsftpd man page in another terminal window to use
	as a reference.

	6) Save the file by pressing the Ctrl and o keys at the same
	time, then pressing the Enter key, then pressing the Ctrl and
	x keys at the same time.

	7) Restart the server with this command to make the changes
	take effect:

	sudo /etc/init.d/vsftpd restart

	8) Close the terminal window(s).
