You can try

    Dim de As String = File.DirRootExternal
    Log ("DirRootExternal = "&de)
    Dim mtc As Matcher = Regex.Matcher("(/|\\)[^(/|\\)]*(/|\\)",de)
    Dim extsdcard As String = de
    If mtc.Find = True Then
        Dim mnt As String = mtc.Group(0)
  
        Log ("mount point = "& mnt)
        Dim dirs As List = File.ListFiles(mnt)
        For Each f As String In dirs
            If storage.isExternalStorageRemovable(mnt&f) Then
                Log ("Device = "& f&":"&mnt&f&" is removable")
                If File.ListFiles(mnt&f).IsInitialized Then
                    Log("probably ExtSDCard: "&mnt&f)
                    extsdcard = mnt&f
                Else
                    'Log("Problem reading "&mnt&f)
                End If
            Else
                Log ("Device = "& f&":"&mnt&f&" is NOT removable")
            End If
        Next
    End If
    Log("extsdcard probably="&extsdcard)
    For Each f As String In File.ListFiles(extsdcard)
        Log(">"&f)
    Next

Thanks for your help.
Although most of my clients have android <5 and I can not use that library.
I have edited the code to go through what is in "mount" and with that I think it will help me.
Regards.
