Ok

If we delete the kwallet directory we would loose both the kwl as well as salt files. Now if we were to call sync, kwl file gets written to disk and user can continue to add data to the wallet untill he closes it, after which he no longer would be able to access it since he doesn't have the salt file with him. Any data that was added to the wallet in the meantime would be lost forever.
