I just come across this brilliantly simple solution if you are using  Net 4 5  not supported this easily in lower versions  and you can use jQuery to make things really simple and painless    Uploading Multiple Files Using jQuery and Generic Handler in ASP Net 4 5  Of course there is the commercial version for classic ASP which can be found at ASP Uploader

The FileUpload AllowMultiple property in  NET 4 5 and higher will allow you the control to select multiple files    lt asp FileUpload ID  fileImages  AllowMultiple  true  runat  server    gt     NET 4 and below    lt asp FileUpload ID  fileImages  Multiple  Multiple  runat  server    gt    On the post-back  you can then     Dim flImages As HttpFileCollection   Request Files                     For Each key As String In flImages Keys     Dim flfile As HttpPostedFile   flImages key      flfile SaveAs yourpath  amp  flfile FileName   Next
