Extract the Files

The VM is packaged in a .rar archive. You can use a tool such as 7-Zip to extract the VM files from the archive.

Open the directory
Here are the VM files
The Kioptix Level 1.vmdk file is what we're interested in. A .vmdk file is a virtual hard disk file. We'll be attaching this to a scaffolded VM and setting this disk as the boot disk.
