Access Hard disk 2 ?

i found this article to add an old VM into my currently used windows 10 VM:

i added the hard disk 2, but can not seem to find how to access those files. the old VM is windows 7 i believe.
I hope i am missing something stupid.
Thanks in advance for any help!

 

Hello, could you provide us with the screenshot of your virtual machine configuration Hard drive settings please?

 

are any of the 3 attached shots what you mean?

 

I believe I was able to get the files i required using the tool "parallels mounter". I tried this originally, but it did not work. I am not sure what changed, but when I just tried it again, the old Windows 7 file structure showed up in my finder hard drives.
thank you.
