RubyMine to ignore some files when going to file

When going to file (Go To => File, ⇧⌘N o开发者_开发百科n Mac OS X), is there a way to have RubyMine ignore some directories? We have a lot of third party code in vendor which I'd rather ignore.

File | Settings | Project Structure, select directory on the right and press Excluded button on top:

The quicker way:

Right-click on a folder in your project tree and click “Mark Directory As” → “Excluded”.
