I am getting the list of subdirectories from a specified directory using
System.IO.Directory.GetDirectories(), and would like to get only
subdirectories that are not hidden or system directories. I did not notice
any way to do this using System.IO.Directory.GetDirectories(). Is there some
other function that I can use, or is there some way to determine whether a
directory is hidden or system? Thanks.

You can use System.IO.DirectoryInfo.GetDirectories to return an array
of DirectoryInfo objects. This object has an Attributes property,
which you can check to see if the system or hidden attributes are
applied.

Could you show me an example of how I test for these attributes? It seems
like the Attributes property has an enumeration containing Hidden and
System, but I am having trouble testing whether they are true for the
current DirectoryInfo. Thanks.

Nathan,

Those attributes are flag attributes - so a simple bitwise and will
tell you if they have the attribute:

Option Strict On
Option Explicit On

Imports System
Imports System.IO

Module Module1

Sub Main()
Dim rootInfo As DirectoryInfo = New DirectoryInfo("c:\")
For Each d As DirectoryInfo In rootInfo.GetDirectories()

If (d.Attributes And FileAttributes.System) <>
FileAttributes.System Then
Console.WriteLine(d.Name)
End If
Next
End Sub

End Module

HTH,
