i want to remove files and directories from an NSS Volume on a OES2Lx

From a remote ncp client its no problem, but very(!) slow. It is not
practiable to delete a few 1000 files & dirs this way.

Whats the recommened way to do this on the server itself? iManager can't
delete recursiv; NRM for OES2Lx? Where?; An ncpmount on the server itself
an then rm -rvf shows: Directory not empty or Operation not allowed.

Any other ideas?
