Classic ASP: All files containing 123 in filename

Using old classic ASP, how can I find all files containing "123" in their filename?  This returns all files:
<%
  Dim strPathInfo, strPhysicalPath
  strPathInfo = Request.ServerVariables("PATH_INFO")
  strPhysicalPath = Server.MapPath(strPathInfo)
  Dim objFSO, objFile, objFileItem, objFolder, objFolderContents
  Set objFSO = CreateObject("Scripting.FileSystemObject")
  Set objFile = objFSO.GetFile(strPhysicalPath)
  Set objFolder = objFile.ParentFolder
  Set objFolderContents = objFolder.Files

  For Each objFileItem In objFolderContents
    Response.Write objFileItem.Name 
  Next

%>

Using "IF" seems like a waste of resources because it would have to go through about a thousand files looking for a match.  In PHP I would use glob() for this:
http://php.net/manual/en/function.glob.php

Is there a similar way to do this in classic ASP?
Dave BaldwinFixer of ProblemsCommented:
glob() does the same thing as the ASP 'IF', you just don't have to see the details in your code.  The resources used are essentially the same.
it_saigeDeveloperCommented:
You are already going through about a thousand files already by the simple fact that you are using a foreach in order to loop through all of the files in the directory (parent folder) of the selected file.  The if statement is required because you want to filter on files that contain "123" in their name.

Unfortunately, the Files collection object, of the FileSystemObject, does not contain such a method that accepts a filter.  .NET, on the other hand, does allow for filtering the contents of a directory listing.
