How do i block a certain subfolder from being indexed?

It is a symlink to a folder that i use for other software, but zenphoto should not index it because it gets stuck in it (to many folders). I cant change the access on filesystem level because that would break my other software.

I have tried the unpublish option but this doesn't stop ZP from indexing the folder.

Is there another option in ZP?

Don't put the folder in the the /albums folder if it should not be indexed.
