Missing additional configuration xml files after build

Hey,

I'm a beginner and the documentation is not very clear. I added configuration files in /Assets/Resources or /Assets/MyDir. After build, there are two parts : => directory_data - Assets/MyDir - unity default resources (where are my files ?) => myApp.exe

Theses files are missing in "directory_data" so i can't modify my xml files.

I'm sure, there is a way to include these files after building and the script could open them or i could change build settings to keep my files.

He seems having the same trouble : http://forum.unity3d.com/threads/35298-How-to-create-a-config-file

How can i fix that please ?

Thank you all.
