Current Access Zone:
From this drop-down list, select the access zone in which you want to manage SMB share settings.
Enable file filters
Click this check box to enable file filtering by file extension. You can deny writes to the share by certain file types, or allow only certain file types to write to the share.
Advanced SMB Share Settings
Click to access a list of advanced SMB share settings relating to permissions, performance and security. We recommend that you do not change any of the default values unless you thoroughly understand the potential effects of those changes.

To change the advanced settings, click Use Custom or Use Default under the appropriate setting title.

Continuous Availability Timeout
Specify the amount of time you want a persistent handle to be retained after a client is disconnected or a server fails. The default is two minutes.
Strict Continuous Availability Lockout
Set to yes to prevent a client from opening a file if another client has an open but disconnected persistent handle for that file. If set to no, OneFS will issue persistent handles, but discards them if any client other than the original opener attempts to open the file. The default is yes.

Sets the default source permissions to apply when a file or directory is created.

Change Notify
Configures notification of clients when files or directories change, which helps prevent clients from seeing stale content, but requires server resources. The default value is Norecurse.

Impersonate Guest
Determines guest access to a share. The default is Never.
Impersonate User
Allows all file access to be performed as a specific, fully qualified user name. The default is no value specified.

Allows ACLs to be stored and edited from SMB clients. The default is Yes.
