If you add some folder as additional source in a flex project, and that folder or a subfolder contains non-as-files, those folders together with the non-as-files will be copied into the bin-debug folder of your project. Even if those files are removed in the source folder, they will remain in the bin-debug folder.

Is it possible to get rid of this behaviour and in that case how?
