Where does Virtualbox store Literally ALL of its Files & Packages?

So I'm thinking of installing Virtualbox on my Ubuntu machine but I'm not completely sure if I actually should. One thing that I am uneasy about is the fact that I don't know where all the files are stored. I am simply installing virtualbox with apt (but not directly downloading the .deb from the website), like this:

sudo apt install virtualbox

I'm not that crazy about what packages are coming with virtualbox, but I'm more concerned about every single file virtualbox adds to my filesystem so I know what to remove and how to remove it if I want to completely remove virtualbox.

Basically, I would like to know all the locations where virtualbox stores every single one of its files.

I'm using Ubuntu 20.04.3 LTS

Solution 1:

Look up the package (and each dependency) in https://packages.ubuntu.com ...

... and Scroll to the bottom of the page...

...and click on the link for "list of files"

Solution 2:

You can get this info from the Properties menu in synaptic...but only for installed packages.

I have virtualbox-6.1 installed, not virtualbox, but here is the information for that (in a pastebin, it is over the 30,000 character limit for an answer :(

FWIW, virtualbox is a wonderful tool, I use it all the time.
