How do I remove a bad file??

[Dennis Wicks <wix@mgssub.com>]

Greetings;

I have a file that looks like the following in an ls list;

-????????? ? ?    ?             ?                ? Inbox.msf

I can't do anything with it. Can't mv, rm, cp, or anything 
else I have thought of to get rid of it or write over it.

Any ideas how I can get this thing out of my life??

Many TIA!!
Dennis
