Hello (and in advance, pardon my ignorance)

I have a nss volume with several thousand directories. I need to delete a
lot of those. My problem is that some subfolder contain directories with
delete inhibit set.

I cannot figure out how to get those flags cleared.

In the good old days I would have used flag.exe (I actually tried that,
but it ran out of memory). How should I clear the DI flag on the volume
from the oes2 box?
