Downloading Multiple Files From FTP

I'm currently using this script to download over 400 txt files which are needed for a project here at work. It works great, however, it will download the ftp files in question (which it gets a list of from another tab) in order. I would like a way to either download all 400 ato nce, or in a batch of 50 or even 100. As it is, the procedure takes around 70 mins to complete. I was hoping of a way to speed it up.

Here is the script I am using.

VB:
Private Declare Function URLDownloadToFile Lib "urlmon" Alias "URLDownloadToFileA" (ByVal pCaller As Long, ByVal szURL As String, ByVal szFileName As String, ByVal dwReserved As Long, ByVal lpfnCB As Long) As Long
Public Function DownloadFile(URL As String, LocalFilename As String) As Boolean
Dim lngRetVal As Long
lngRetVal = URLDownloadToFile(0, URL, LocalFilename, 0, 0)
