for saving whatever changes you have made, you need to have first created a folder:

il2\MAPS\TheSameNameYourMapHas (probably you will have to create from \MAPS\... on, including MAPS)

and your savings (full savings, i.e., save) will be in that very folder, not in your real map folder. For making changes effective you just need to cut and paste.
