Do you really feel this needs to be uploaded here? Why not try something of your own, with your own ideas, at least it would be something original. It can’t even be justified as a convenience for vanilla JJ2 since these levels can already be imported into the base game, as a matter of fact all Secret Files levels apart from Town 3 can be, so this is a pretty pointless upload with the winter themed tileset being the only thing that’s different compared to the original levels. All it does is show how basic some of the Secret Files level layouts were.
Try something of your own!
