Excel VBA: Search for a directory - vba

Question

In vba, I would like to search through directories for a specific directory name. Ideally the searching time would be fast (similar from a windows search).
from different sources, I could build a script (given bellow) with a recursive sub program. The script works but it is very slow as soon as the hierarchy is a little complex.
Is there a way to make the search faster?
Sub GetFolder(Folder As String, searchF As String, colFolder As Collection)
Dim SubFolder, subF As New Collection, sf As String
If Right(Folder, 1) <> "\" Then Folder = Folder & "\"
If Dir(Folder & searchF, vbDirectory) <> "" Then colFolder.Add Folder & searchF & "\"
sf = Dir(Folder, vbDirectory)
Do While Len(sf) > 0
If sf <> "." And sf <> ".." Then
If (GetAttr(Folder & sf) And vbDirectory) <> 0 Then
subF.Add Folder & sf
End If
End If
sf = Dir()
Loop
For Each SubFolder In subF
GetFolder CStr(SubFolder), searchF, colFolder
Next
End Sub

I think you are underestimating the hierarchy size. Change your code to this one to see how many folders you are recursing through.
Option Explicit
Sub GetFolder(Folder As String, searchF As String, colFolder As Collection, ByRef counter As Long)
Dim SubFolder, subF As New Collection, sf As String
If Right(Folder, 1) <> "\" Then Folder = Folder & "\"
If Dir(Folder & searchF, vbDirectory) <> "" Then colFolder.Add Folder & searchF & "\"
sf = Dir(Folder, vbDirectory)
Do While Len(sf) > 0
If sf <> "." And sf <> ".." Then
If (GetAttr(Folder & sf) And vbDirectory) <> 0 Then
Debug.Print Folder & sf
counter = counter + 1
subF.Add Folder & sf
End If
End If
sf = Dir()
Loop
For Each SubFolder In subF
GetFolder CStr(SubFolder), searchF, colFolder, counter
Next
End Sub
Public Sub TestMe()
Dim newC As New Collection
Dim colChecked As New Collection
Dim counter As Long
GetFolder "C:\Users\<username>\Desktop\BA Tools", "v", newC, counter
Debug.Print counter
End Sub
What is the number that you get at the end of the code, when you run it?
