folder delete

LS.
Netware 6.5 (sp7). we have a folder on volume1 that we cannot delete.
in this folder are several files, only visible thru the Netware Console.
When looking with Windows Explorer the files are NOT shown. Reason, in the
folder exists a file with a strange character and is 0Kb in size (corrupt).
But we cannot delete this file with Netware console (GUI) or thru the
Netware webbrowser.
What can we do to delete this?
