Ah, I see. That's just how it's all formatted. To download the file, look tot he far right (the column called "DOWNLOADS") and you'll see file extensions, such as "DOC", "PDF", "ZIP". These define the filetype.
Doc = word document
PDF = Acrobat Reader document
Zip = compressed folder.
Anyway, you're machine likely has the facilities to open all of these formats. Simply click on the extension which lies on the same row as the file you want to download.
