The root drive (C:\) is shared, nevertheless there is no access to subfolders,
How come that the root drive (C:\) is shared but no access is permitted to a particular subfolder (attached)?
How to force the sharing for the root and ALL the subfolders
Thank you

In addition to the sharing, you must check that both share and file permission are granted on the connected user for the folder to be visible, even with full disk being shared.
Particular from your screenshot, by default SQL Sever applies specific permissions on its data folders, granting only admins, the service account and system access to it. Most likely it will fail with the same error if you navigate normally on the local machine, not from the share.
Just right click on the folder (not in a file as you're doing in the screenshot), click properties, security tab, add, select the user and give him read or write access as needed.
BTW, and again particular for what is seen in the screens, it's generally not a good idea to manually touching files in the data folder of SQL Server, they're best handled though a normal connection with a query. Most times, the server will simply block the files when attached to the server so you can't even read them, from network or not.
Many thanks Alejandro85 for the answer.
That was my original issue! I gave the root folder sharing + security to everyone (!), nevertheless, I got the message shown in my first post.
By the way, I couldn’t even know the difference between the sharing and security properties (attached)! Are they doing the same kind of thing?

Both the sharing and the security tab are very similar, they set permissions but work on different levels.
The sharing permissions work only on network accesses though Windows shares, users must be granted permissions here to be able to view files though the network, even though they can access locally.
The security tab works for every access, no matter how it's made. It controls both local access and network too, and can be set at a file level and folder by folder (sharing permissions work on whole shared folders).
To use a file though the network, you need BOTH sharing permission and security tab permission.
Now, the problem I guess is that on the security tab, you've assigned permission to the root folder only. Some folder don't automatically inherit those permissions and apply their own (program files, windows folder, users folders are examples of those). SQL Server also apply custom permissions and ignore the parent's ones. That's why I said before that you should look there, at the SQL data folder, not the root of drive.
