Type FileInfo (name As String, lastModified As Long, size as long)   'size in bytes

Public Sub CreateFileInfo (name As String, lastModified As Long, size As Long) As FileInfo
    Dim t1 As FileInfo
    t1.Initialize
    t1.name = name
    t1.lastModified = lastModified
    t1.size = size
    Return t1
End Sub


Private Sub SortedList as List

    Dim lst As List
    lst.Initialize

    For Each f As String In File.ListFiles(log_dir_pdf )

        If f.ToLowerCase.EndsWith("pdf") Then
    
            Dim fInfo As FileInfo = CreateFileInfo(f, File.LastModified(log_dir_pdf, f), File.Size(log_dir_pdf, f))
            lst.Add(fInfo)
            
        End If
    
    Next
    
    lst.SortType("name", True)    'or "lastModified", or "size"
    
    Return lst

dim filesize as Long=File.Size(Dir As String, FileName As String) As Long

    Dim d As Long = File.LastModified(path, filename)
