importing models?

How do I do this I got some cool models from the site, but don't know how to get them in my map. They say to put them in the units directory, I cant find this. I thought I had it before however I cant find it. I went under my war3 directory, searched every folder but none are units. I remeber back in the day when I had one of the enhanced editors, before FT came out I had a units/doodads and all those kind of folders but now none :(. So when I do find it if I do, I just put all 3 files there, then go to the unit editor then put that model as him? Yes I already did use import manager

Make a new folder called Units and put hte models in there.

It's cause before going into the MPQ it checks there first, so any models you may have should go there.

I think... though I'm not positive.
