A lady "put together a virtual machine" that was supposed to include a certain software and related packages. I was given a folder of files (vmdk, log, vmxf, plist, vmsd, nvram, and png files) and told to use VirtualBox. I honestly hardly know where to start. I downloaded virtual box. In the VirtualBox window that came up I clicked new.
I have tried two different things. First I tried to "use an existing virtual hard disk file" while creating my virtual machine. That didn't work, or maybe I just don't know how to make it work. 
Second I made my virtual machine by creating a virtual hard disk. Then I went into settings, selected storage, and tried to open the file. That didn't end up working. 
Am I even on the right track? Does anyone have any suggestions for doing this?
