When you make a map in editor and save it does that take memory up on your PC? Also how do you delete maps you no longer want. I've went on them and go to exit and clicked don't save but it doesn't go away. I'm on win 10 and finding folders is a nightmare.
I am assuming you mean drive space and not memory. The easiest way to find the folder would be to do a file search for *.fc4map . Then delete the maps you no longer want.
