I can check the write-access to a folder by trying to write a file in it. But, I am looking for a more elegant solution.

I am testing it using Ensemble-service and terminal both. The results are the same.

I tried issuing "Open" command on a directory. But it always returns the failure "NOTOPEN", irrespective of the fact whether the directory has write-access or not. So, this does not resolve the issue I am facing.
