Eclipse: How to add an existing source folder? -

I have a directory named c: \ RemoteSrc under it there are 3 directories which are currently source folders (I think? The icon is an open folder with a small orange grid) In my eclipse project I have left a new directory under c: \ RemoteSrc, which I want to add to my project.

But

If I right click on my project and "Create Path" "-" Link Source "and try adding it to the" Folder already exists "with a different case" Yes, I know that the folder already exists, so im trying to include it in IT

I think that you need to refresh the project assuming the folders automatically Or file) in your project directory.
