This is really only an issue if you've been moving the files around within folders. If you've moved a batch of files within folders, they would typically remain in the same structure and thus finding one, would allow the system to recreate the path to the rest of them. While there is a fix for this coming, my recommendation to any DJ is always to take care of what you're doing with your collection and don't give your software a reason to lose your files -- move them to their destination before you import them.
