getting in shape

So I downloaded a bunch of files for the Wisconsin counties from the The Census 2000 TIGER/Line (linked from the ESRI site). The data for each county came in its own compressed folder with a shape file, as well as a .dbf and .shx file (which I wasn't really looking for). I had to uncompress each of the 72 folders and copy the shape file into another directory. Is there an easier way in windows? I know with linux/mac i could have a shell script do this!

Anyway, I then imported the shape files into ArcGIS and, lo and behold, up popped the state of Wisconsin with all the counties. Except ... I notice all the counties on the eastern side are not the correct shape. They're stretched horizontally. Is there a problem with the data? Do I need to tweak something in ArcGIS?

Check the projection that's being used on the map. Setting map projections was mentioned in our last tutorial (though we didn't cover it in class).
