Files that you create or rename on volumes that use the NFS name space (that is, volumes in either NetWare or UNIX modes) must observe the standard UnixWare filename conventions:
With the NFS name space loaded on a volume, UnixWare filenames are translated to DOS filenames and it is the DOS filenames that will be seen by any client that does not use the NFS name space.
So, if you log into the NetWare server from a client that uses only the DOS name space, your files may appear to have different names than the ones you see from UnixWare. (From UnixWare, your files will always have the names you give them.)
The name translations done on the DOS side are as follows:
If the addition of digits to the filename causes it to reach 8 characters (or if it is already 8 characters long), then characters are grabbed from the end of the filename and replaced with successive digits until a unique filename is found.
