[PATCH] Overwriting hidden files fails

[Miguel Medalha]

I don't know whether this is related to the subject at hand but I will 
report it anyway in case it might be helpful for me and others.

In Windows Explorer, when I try to delete a folder with all its contents 
and the folder contains a Windows "Thumbs.db" file, deletion fails with 
a message stating that the folder cannot be deleted because it is not 
empty. All deletion attempts fail. But then, I go to Folder Options and 
select "Show hidden files, folders and drives", I am immediately able to 
delete the "Thumbs.db" file and consequently the folder, i.e. once the 
hidden file is shown it can be deleted. This is Windows 7 as client to 
Samba 4.4.2and 4.4.4.
