VBA - Folder Picker - set where to start [duplicate]

Question

I have a small Access VBA application that requires users to select a folder. I was wondering if there is a way to tell VBA the path at which to start the folder picker. i.e. start the folder picker at C:\data\forms. Currently it seems to be starting from the directory that was previously used. Also is there a way to limit what the folder picker can access. So it can access anything within C:\data but not anything else in C:

I have been using the following code (Not My Code) successfully for many years.

Sub Sample()
    Dim Ret

    '~~> Specify your start folder here
    Ret = BrowseForFolder("C:\")
End Sub

Function BrowseForFolder(Optional OpenAt As Variant) As Variant
     'Function purpose:  To Browser for a user selected folder.
     'If the "OpenAt" path is provided, open the browser at that directory
     'NOTE:  If invalid, it will open at the Desktop level

    Dim ShellApp As Object

     'Create a file browser window at the default folder
    Set ShellApp = CreateObject("Shell.Application"). _
    BrowseForFolder(0, "Please choose a folder", 0, OpenAt)

     'Set the folder to that selected.  (On error in case cancelled)
    On Error Resume Next
    BrowseForFolder = ShellApp.self.Path
    On Error GoTo 0

     'Destroy the Shell Application
    Set ShellApp = Nothing

     'Check for invalid or non-entries and send to the Invalid error
     'handler if found
     'Valid selections can begin L: (where L is a letter) or
     '\\ (as in \\servername\sharename.  All others are invalid
    Select Case Mid(BrowseForFolder, 2, 1)
    Case Is = ":"
        If Left(BrowseForFolder, 1) = ":" Then GoTo Invalid
    Case Is = "\"
        If Not Left(BrowseForFolder, 1) = "\" Then GoTo Invalid
    Case Else
        GoTo Invalid
    End Select

    Exit Function

Invalid:
     'If it was determined that the selection was invalid, set to False
    BrowseForFolder = False
End Function
