Exclude project\folder from “Navigate Files” in IntelliJ

Question

I'm developing a Grails application with IntelliJ. Many time happens this: When i try to find a file by this shortcut :

Ctrl+Shift+N

IntelliJ find the source file and the 'compiled' (same) file (Because grails plugin imported into a grail app, copy entirelly his folder).

There is a way to hide project-files from "Navigation File" functionality?

Thanks
