An .nfs* file is created when an open file is removed from an NFS share. In other words, when a process has a file open on an NFS share, and the file is removed by another process, an .nfs* file is created. When the original process closes the file, the .nfs* file is removed.

Example:

(system1) $ echo testdata > /NFS_volume/shiznit
(system1) $ tail -f /NFS_volume/shiznit

(system2) $ rm /NFS_volume/shiznit
(system2) $ ls -a .nfs*
.nfs00222d9e00000001
(system2) $ cat .nfs00222d9e00000001
testdata

(system1) $ Ctrl-C
(system1) $ ls -a
