I agree with that but I need this functionality for an ibay with MS Access database file.
The ibay with database is visible via Netwok Neighborhood on Win clients. There have to be a protection that users don't delete this file by mistake.
They access it via application program and they use it according their user rights. They can't simply delete all the data via application but they are able to delete database file while they are browsing the network which is very unpleasant

.
I think that there have to be some settings in smb.file to protect data share (ibay) from deleting the files that they are located in it.
