How to format 'My Book 4TB'?

[Bradex]

1. Is it necessary to format my book before its first use?
2. Will formatting retrieve the ‘additional files’ shown in WD SmartWare?
3. What is the best way to format: Windows disk management, Drive erase (in WD Drive utilities) or WD quick formatter for windows?
4. Will formatting the following folders which came with my book: Extras, Locale, User manuals, WD apps for mac/windows. Is deleting them safe?

It should be formatted and ready for use on Windows as long as it was not a model for Mac.

I have started using it without any further formatting. I left untouched all the files which came with my book. Seems to work well for now!
