is there an API/published format for the IE favs files?

The dude at The Furrygoat Experience has a CheckFav util which apparently checks for dead urls in IE favs files on disk. Need to find out what APIs he used to read favs files....I recall looking madly for these to make a private version of the old ClickMarks service.

I know...I know...there are other online bookmark managers...but I was on a quest to do it myself.

I'll have to hit this guy up once his CheckFav Wiki is running again.
