No! files like .nfsXXXXX indicate that you are working in an nfs mounted
directory. Probably you a running program has a file open that you are
trying to delete.  The fact that you cannot remove this file is normal
behaviour, You shouldn't even be the owner of the file.
A discussion about .nfs files is sumarized at
http://www.netsys.com/sunmgr/1998-04/msg00123.html

I just quote a snippet:

<quote>
from the man page nfs(4P) (SunOS 4.1.3, but it is the same in Solaris 
2.x):
 
     When a file that is opened by a client is unlinked  (by  the
     server),  a  file with a name of the form .nfsXXX (where XXX
     is a number) is created by the client.  When the  open  file
     is  closed,  the  .nfsXXX  file  is  removed.  If the client
     crashes before the file can be closed, the .nfsXXX  file  is
     not removed.

This file is not correlated to your cpmd2cube problem.

BTW, the abstraction from nfs on one unix-like system to another is not
much, so most of the above mentioned posting is valid on AIX, too.
