Here’s a recent discussion about file access control, which includes a discussion of how to log in to the MyCloud’s linux OS, and modify file permissions directly, rather than via the SMB file server.
The MyCloud is a Network Accessed Storage device; a computer (running embedded linux), which provides a file server, holding your files on a hard disk. It is accessed via ethernet.
The files on the MyCloud, as seen by Windows, are ‘owned’ by the SMB file server running on the MyCloud.
The SMB file server reflects the file permissions assigned by linux, running on the MyCloud.
There are three categories of user, each with permissions; owner, group, all. The owner and group will be what you are seeing as Linux User and Unix Group.
The MyCloud user access sorts out the user and group permissions.
