How do I access/delete files in private folder - Mac

Pls Help. I have a private folder with admin full access. Able to open up the hidden folder through " Connect to Server"

Here the issue. Am able to drop files in but I can’t see it? How am I to manage it? 

Hope my question is clear.

How are you connecting to the folder?

You can just type smb://mybooklive/sharename and you should see the files on that share

only reason it will not show is if they were copied using a backup software or if the files were not transferred at all

Somehow is working as per you described.  Thanks

sure, any time.
