If the clients can only access and view a subset of files or folders present in a shared folder, it might be for one of the following reasons:
1. Share and NTFS permission
Please check if you have granted the users with the different Share and NTFS permissions on these share folders and files. We need to verify that the user have permission to access the misrepresented folder.
2. Hidden Share folders
Please check if there are any hidden share folders on the file server.
3. DFS share with Access-Based Enumeration.
When the client connects to DFS share and Access-Based Enumeration is enabled on these share folders at the same time, Windows Explorer will not display files or folders that a user does not have right to access.
