The .nfsXXX file is a sign that some process still has that file open.
If you forcibly delete the file, you are very likely to screw up that
process. Better then just to kill the process.

You might be able to move the file to another directory, but the problem
then is that the process that tried to delete the file may not have
write access to that directory. In this case, the unlink may fail, and
you will be left with a dangling .nfsXXX file.

As far as the NFS server is concerned, this is a file just like any
other. The server attaches no special meaning to it.
