>>>I created a folder (in the application folder of VS 2012) Data_sets (so my directory tree is now App_Name\Data_Sets. Then I copy dataset file MyDataSet.xsd to the folder Data_Sets.

If you don't want that to happen then, after creating the folder open its Properties window and set 'NameSpaceProvider' to false.

If the folder is just there as an ide 'organizational' thing I usually turn NameSpaceProvider off but I guess it's mainly a question of taste....
The option wasn't there in early VS versions....
