Description Jaroslav Tulach 2010-03-25 09:16:58 UTC 
There is no reason why fileObject.getParent() shall require a disk touch (if the system believes fileObject.isValid()). Currently it may, if the parent FileObject has not yet been created. 

It is important for bug 180061 (which wants to use kind of hierarchical cache) to make getParent() as lightweight as possible.
