Multiple drive search.

Hi iv been struggling with this for a while and cannot figure out how to do a multiple drive search. ie Drive C: D: E: etc
Here is the code I am using.

VB Code:

Private Sub Form_Load()
    Dim strStartPath As String
    strStartPath = "C:\"
    ListFolder strStartPath
    Dim ff As Integer, x As Integer
ff = FreeFile
Open "C:\CC\FileLo.LOG" For Output As #ff
  For x = 0 To List1.ListCount - 1
    Print #1, List1.List(x)
  Next x
Close #ff
End Sub
Private Sub ListFolder(sFolderPath As String)
On Error Resume Next
    Dim FS As New FileSystemObject
    Dim FSfile As File
    Dim FSfolder As Folder
    Dim subFolder As Folder
    Dim tabcount As Integer
        Set FSfolder = FS.GetFolder(sFolderPath)
    For Each FSfile In FSfolder.Files
        DoEvents
''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''
        If FSfile.Name Like "ArmyOps.exe" Then
            List1.AddItem FSfile
        End If
''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''
    Next FSfile
    For Each subFolder In FSfolder.SubFolders
        DoEvents
        Call ListFolder(subFolder.Path)
    Next subFolder
    Set FSfolder = Nothing
End Sub
