I am creating a project that will populate a Tree View with information
from a Cd, Zip, or Floppy. I have the user selected the files they
want to copy.

Exampe: A:\ (Directory)                            X

                    - ABC1234 (Folder)               X
                       - Test.html (File)                X
                    - ZXY4567 (Folder)
                       - WTY5678 (Folder)           X
                          - Test2.html (File)           X
                    - Budget.xls (File)

X = items that the user selects

I want to be able to go through all the Tree Nodes and get the files
that have been selected. If the folder above the item is not selected I
still want the code to go into that folder to see if an item is
selected.

If someone could point me in the right direction I would greatly
appricate it.

Take a look at this, I just posted it to help someone else. I only needed
to modify the search criteria to send to you.

'//Initial usage
'//Dim oChecked as Arraylist = Walktree(me.treeview1.nodes)

Private Function WalkTree(ByVal PNodes As TreeNodeCollection) As ArrayList

    Dim oRet As ArrayList, iCount As Integer
    Dim iTemp As ArrayList

    oRet = New ArrayList
    iCount = -1

    For Each node As TreeNode In PNodes
      If node.Checked Then
        oRet.Add(node)
      End If

      iTemp = WalkTree(node.Nodes)
      oRet.AddRange(iTemp.ToArray)

    Next

    Return oRet

End Function
