I'm trying to write something like Total-Commander in C#. I have got problem - when I try to get info about folders like C:/, G:/ or, for example C:/ProgramData there is an exception System.UnauthorizedAccessException. I have already set an Admins permissions in manifest, but it is doesn't help.
Can anybody tell me if this is real to get access to this folders or no ? To make this question more clear left code and screenshot below. Screenshot: enter image description here

}
foreach (FileInfo file in nodeDirInfo.GetFiles())

Thank you in advance
