Unable to open the physical file "xyz.mdf". Operating system error 5: "5(Access is denied.)".

I downloaded some project from here, this included some test MS SQL Server database file called 'SchoolDB.mdf'. I tried to attach it in SQL Server Management Studio 2017.

SSMS throws error as -

Attach database failed for Server 'VSPLBLRLT0231'.  (Microsoft.SqlServer.Smo)

Got solution from here

Now you'll be able to attach .mdf file in SSMS. But the problem is database name having full file path. You can simply rename that in SSMS.
