Help with ASP Collection Object

Hi

I'm new to ASP, so this is a simple problem...

The following code lists the sub folder names in a specified directory.  Rather than loop through the list I want to just pull out the n-th name in the collection.  How do I do this please?  Also is there a property that tells me how big the sub folders collection is?

Set fso = server.CreateObject("Scripting.FileSystemObject")
Set fo = fso.GetFolder(server.mapPath("/images/banner"))

Set fc = fo.SubFolders
For Each f in fc
    Response.Write(f.name & "<br/>")
Next

Cheers
