Can't find Multipass Ubuntu files on Mac M1 Finder

I'm running macOS 11.2.1 on a Mini M1 with one internal and two external drives. Using multipass 1.8.1+mac to create an Ubuntu 20.04.3 LTS instance in terminal. Once in terminal, I can find the 3rd party software I installed while in the shell. However, when I want to find some of the files I see in Ubuntu on the Mac drive, I cannot find them. I clearly don't understand the relationship between the file system in the ubuntu shell and the Mac File system. As an example, this is from Ubuntu

ubuntu@primary:~$ ls
Home  findtestfile.txt  mycroft-core  snap  var

I even created a txt file so I would have something easy to search on, but these files and folders are not together anywhere on the Mac system using Finder (and showing hidden files). Where are they? Help!

Solution 1:

Correct, they're not in your Mac filesystem.

Multipass controls Virtual Machines. Your Ubuntu data and applications are on the Ubuntu VM virtual hard drive. The entire virtual hard drive is usually stored as a single file on your Mac filesystem.

That single file is generally NOT readable by the Finder -- it's readable only by the VM application (multipass/hyperkit or multipass/virtualbox).
