You can specify how long to keep the files in the Recycle Bin and how large the Recycle Bin can get 
before files get permanently erased. 
Advanced CIFS Permission 
The Advanced CIFS Permission box offers options for setting the default permission of new files 
and folders created via CIFS.  The default permission of newly created files is read/write for the 
owner and owner’s group and read-only for others (i.e. everyone).  Permission for newly created 
folders is read/write for everyone.  If the default doesn’t satisfy your security requirement, you can 
change it here. 
Opportunistic locking (often referred to as oplocks) enhances CIFS performance by allowing files 
residing on the NAS to be cached locally on the Windows client, thus eliminating network latency 
when the files are constantly accessed.
