Help with website statistics

I’ve had this site for my sister since 2005 sometime. Its

So the other day my sister asked to pull some statistics for her on put 'em on a chart or something.

So what I can pull from the hosting site is Hits, Files, Pages and Visits.

I cant tell the difference between hits and visits though, And how do I know if they’re unique hits/visits? or is that the difference?

I’m guessing pages is the amount of pages you go through. But the site only has the index with the SWF in it. So that should be the same as the hits and/or. But it isnt. Or do they count page reloads as a page?

I have no idea what they mean by files :S.
