Launched application is not opening level, but editor is

To open a level I used “open level by name” and used both : “myMap” and “game\maps\myMap” which both works in the editor. I launched the application but when I play it fails to open the level. The only way it works is if I set “cook all under content folder” to true, but this makes the game size very large. How to open the level in the launched version just like in the editor but without cooking everything?

I’ve added [AllMaps] inside DefaultEditor.ini and this fixed the problem.
