mdf and ldf file security issue

Hello,

I am using SQL Express 2008 r2 server in Windows 10. I have created a database and when I look into mdf and ldf files properties in Windows Explorer it tells me "You must have read permission to view properties of this object"

Image may be NSFW.
Clik here to view.

I am the Admin in my PC and I am the sysadmin in SQL server. But still why it is showing like this. I know I can take the ownership and then set permissions but still why it is telling "I dont have read permission to this object" ?

Please help.
