Migration of Windows files

Hi

New to MacBook so please bear with me.

I have gigabytes of data on my Laptop running Windows 7. I want to migrate my Outlook files and accounts to MacBook.

The tool supplied on Apple's site appears to be for wireless connection only and takes an eternity failing after a couple of hours.

Is there a way to use a similar method but to an external hard disk.

I am reluctant to do it manually as I am unfamiliar with Mac OS and file storage.
