Get list of sub-directories in VBA

Question

• I want to get a list of all sub-directories within a directory.
• If that works I want to expand it to a recursive function.

However my initial approach to get the subdirs fails. It simply shows everything including files:

sDir = Dir(sPath, vbDirectory)
Do Until LenB(sDir) = 0
    Debug.Print sDir
    sDir = Dir
Loop

The list starts with '..' and several folders and ends with '.txt' files.

---

EDIT:
I should add that this must run in Word, not Excel (many functions are not available in Word) and it is Office 2010.

---

EDIT 2:

One can determine the type of the result using

iAtt = GetAttr(sPath & sDir)
If CBool(iAtt And vbDirectory) Then
   ...
End If 

But that gave me new problems, so that I am now using a code based on Scripting.FileSystemObject.

Answer 1

Updated July 2014: Added PowerShell option and cut back the second code to list folders only

The methods below that run a full recursive process in place of FileSearch which was deprecated in Office 2007. (The later two codes use Excel for output only - this output can be removed for running in Word)

1. Shell PowerShell
2. Using FSO with Dir for filtering file type. Sourced from this EE answer which sits behind the EE paywall. This is longer than what you asked for (a list of folders) but i think it is useful as it gives you an array of results to work further with
3. Using Dir. This example comes from my answer I supplied on another site

1. Using PowerShell to dump all folders below C:\temp into a csv file

Sub Comesfast()
X2 = Shell("powershell.exe Get-ChildItem c:\temp -Recurse | ?{ $_.PSIsContainer } | export-csv C:\temp\filename.csv", 1)
End Sub

2. Using FileScriptingObject to dump all folders below C:\temp into Excel

Public Arr() As String
Public Counter As Long

Sub LoopThroughFilePaths()
Dim myArr
Dim strPath As String
strPath = "c:\temp\"
myArr = GetSubFolders(strPath)
[A1].Resize(UBound(myArr, 1), 1) = Application.Transpose(myArr)
End Sub


Function GetSubFolders(RootPath As String)
Dim fso As Object
Dim fld As Object
Dim sf As Object
Dim myArr

Set fso = CreateObject("Scripting.FileSystemObject")
Set fld = fso.GetFolder(RootPath)
For Each sf In fld.SUBFOLDERS
    ReDim Preserve Arr(Counter)
    Arr(Counter) = sf.Path
    Counter = Counter + 1
    myArr = GetSubFolders(sf.Path)
Next
GetSubFolders = Arr
Set sf = Nothing
Set fld = Nothing
Set fso = Nothing
End Function
