Remove the original 4 episodes from The Secret Files, and the Shareware Demo, and you'll be fine. TSF was meant as an add-on, but was turned into a seperate game instead with its own .exe file instead of a patch (Same goes for Christmas Chronicles). The initial release did come with the full version JJ2 for free on a seperate CD, that's the one I got. There's also a Polish version that had the two games combined if i'm not mistaken.

And you may want to add this little tidbit of info: TSF and Christmas Chronicles came with a collection of User Levels, TSF had the best User Levels at the time (chosen by Steven Wakeman of Jazz2City) and Christmas Chronicles had contest entries of the Easter Level Contest, held at the release of TSF by the now defunct Project 2 Interactive.
