I'll be taking a look using a hex editor, which is essentially looking at the raw bytes. Technically any file can be "opened" using a hex editor (since a file is just a collection of bytes) but making sense of it takes knowledge about how these things work, and lots of practice.
In any case I'm downloading it now so I'll try to see if there's any useful data and maybe find a way to extract/convert the files.
