Hi Taff
(PDF)Portable Document Format is a file format used in Adobe Acrobat Reader.
If you havent already download a free copy of Adobe Acrobat Reader 5 and then you will be able to read any PDF files.
When installing software form CD's they somtimes ask if you wish to install the acrobat reader witch come with the software so instead of having a paper based book, alot of companys are now giving you the book in PDF format on CD which i supose save them money.
Hope this helps m8
