Comment 8 for bug 676767

I don't think this will help but looking through the restored files a few
weeks after I noticed a couple had restored and had no name, logo or
properties, they are just files??? I really don't know what they were
originally, but chances are they were from an old windows program. I do
still have the backup set but its nearly 200gb.
