Note:
 It is very important to remember the encryption key. It is strongly recommended that you export and save the
encryption key. If you forget or lose the key, there is no way to rescue the encrypted data.
 If an encrypted folder is unmounted, you cannot rename it or change its volume location.
Define Windows ACL Privileges for Shared Folder
Go to Main Menu > Control Panel > Shared Folder to define ACL privileges for a shared folder. Windows
Access Control List (ACL) is a list of privileges or permissions that determine specific access rights under the
Windows environment. This can help administrator define access control rules for an individual file or a directory,
and give different access rights for individual user or group.
Through Windows ACL, you can assign different privileges to local and domain users in the system. The
privileges apply to all file-related applications, such as FTP, File Station, NFS, AFP, WebDAV, etc.
To define Windows ACL settings for a shared folder:
1 Go to Main Menu > Control Panel > Shared Folder.
2 Click Create to create a shared folder, or select an existing shared folder and click Edit to edit the folder.
3 Under the Shared Folder Info tab, enter the fields required.
4 Under the Windows ACL tab, click Allow editing Windows Access Control List.
5 Click OK to finish.
To edit Windows ACL settings using File Station:
Go to Main Menu > DSM Help, and then go to Control Panel > Shared Folder > Windows ACL for detailed
instructions.
To edit Windows ACL settings using Windows Explorer:
Refer to the How To article for detailed instructions.
When there's a conflict between Windows ACL settings and the shared folder privileges, the system will
automatically adopt the settings the two may have in common. For example, if the shared folder privilege is
"Read/Write", but ACL privilege is "Read". Then final privilege will be only be "Read".
