when FLDR returns access denied

THANKS!

For Each FLDR As String In My.Computer.FileSystem.GetDirectories("D:\Setup", FileIO.SearchOption.SearchAllSubDirectories, "*")
            MessageBox.Show(FLDR)
        Next

May you should try searching specific folders instead of the entire c drive which can have access restriction on certain folders (System folder for example)

There is no way to handle that exception and complete the search. I think that is a big oversight with that method but you can only work with what you've got. If your folder tree may contain inaccessible folders then you have no choice but to perform your own recursive search. That way you can simply ignore an access denied exception and move on to the next folder:

Public Function GetDirectories(ByVal path As String) As List(Of String)
    Dim subfolders As New List(Of String)
 
    For Each subfolder As String In IO.Directory.GetDirectories(path)
        subfolders.Add(subfolder)
 
        Try
            subfolders.AddRange(GetDirectories(subfolder))
        Catch ex As UnauthorizedAccessException
            'Ignore this folder and move on.
        End Try
    Next subfolder
 
    Return subfolders
End Function
