Agree with @fuzztone , but @designsfx makes a good point, many systems use a version of the Unix operating systems to format data as it's a much cheaper license then the Microsoft format of data. Ask Cocktail, they will tell you. If it is a Unix version, have a computer store do it for you. Although you can do it yourself, unless you are very good with computers (moderate isn't good enough, sorry to say) and the right software, it's not worth your time or effort.
Just FYI, I am a retired CIO, so I am very familiar with the process converting Unix data to another format.
