Exclude path from scan

[Acrobater]

Hey guys I have this code to scan my folder and list the files in a listbox:

Dim LOCAL = "F:\Family"
        'Dim LOCAL As String = My.Computer.FileSystem.GetFiles("F:\Family", FileIO.SearchOption.SearchAllSubDirectories)
        Dim xmlFiles() As String = Directory.GetFiles(LOCAL, "*.xml", SearchOption.AllDirectories)
        Dim srtFiles() As String = Directory.GetFiles(LOCAL, "*.srt", SearchOption.AllDirectories)
        Dim aviFiles() As String = Directory.GetFiles(LOCAL, "*.avi", SearchOption.AllDirectories)
        ListBox2.Items.Clear()
        ListBox1.Items.Clear()
        For Each avi As String In aviFiles      
            If Array.IndexOf(xmlFiles, avi.Replace(".avi", ".xml")) >= 0 Then
                ListBox1.Items.Add(avi)
            ElseIf Array.IndexOf(srtFiles, avi.Replace(".avi", ".srt")) >= 0 Then
                ListBox1.Items.Add(avi)
            Else
                ListBox2.Items.Add(avi)
            End If
        Next

Is there an option to exclude one path inside the "LOCAL"? Like scan and list everything but "F:\Family\Pictures", "F:\Family\Texts"...

Thank you.
