I noticed something:

It says, you can only open a direcory with FILE_FLAG_BACKUP_SEMANTICS...
Maybe this is why its causing "AccessDenied".
But on the other hand, the list of functions to call do not contain
FlushFileBuffers! Wo it might be useless.
Unfortunately, we cannot do this from Java NIO.2, but you may try this from
.NET:
