I'm away from my usual machine, so I don't have all my tools to hand. But on a Windows XP machine, changing it to .zip and trying to Extract All using the built-in de-zipper gives two mysterious warnings about password protected files. The file names given seem to be gibberish. Perhaps it's a (slightly) corrupted zip file?
The only weird thing is that there seems to be four odd characters at the start of every paragraph. As I said, I'm not at my usual machine, so I can't tell what these are exactly. Perhaps they're fixed width spaces to give an indent. In which case - ugh!
