[mdlug] Mystery file system

[Robert Adkins II]

Is it possibly an "unclosed" Burn?

Some programs will allow you leave "open" a burn session in order to let you
continue to add more data without it writing out a Table of Contents,
chewing up space on the disc. I am unsure if you would see what you are
seeing when you receive such a disc.
