I haven't seen this on VBC using the filesystem object or a collection. very neat and fast since you don't need to go through it twice to redim an array. the only slow down with this code is the print statement.
API DeclarationsDim colDirs As New Collection
Dim objFso As New FileSystemObject
'make sure under Project|References
'you have Microsoft scripting Runtime checked
VBcodersPrivate Sub Command1_Click()
Dim lForIndex As Long
Set colDirs = Nothing
Set colDirs = New Collection
Me.List1.Clear
DoEvents
colToFill.Add Item:=endInSlash("C:")
Call makeTree("C:", colDirs)
For lForIndex = 1 To colDirs.Count
Debug.Print colDirs.Item(lForIndex)
Next lForIndex
End Sub
Sub makeTree(ByVal inPath As String, ByRef colToFill As Collection)
Dim objDir1 As Folder
Dim objDir2 As Folder
Dim sCurrentDir As String
sCurrentDir = endInSlash(inPath)
Set objDir1 = objFso.GetFolder(sCurrentDir)
For Each objDir2 In objDir1.SubFolders
colToFill.Add Item:=sCurrentDir & objDir2.Name
Call makeTree(sCurrentDir & objDir2.Name, colToFill)
Next objDir2
Set objDir1 = Nothing
Set objDir2 = Nothing
End Sub
Function endInSlash(ByVal inString As String) As String
If Right$(inString, 1) <> "\" Then
endInSlash = inString & "\"
Else
endInSlash = inString
End If
End Function
