List All Filenames In Directory On Worksheet (including Subfolders Contents)

I was wondering if there is a way to list all filenames from a directory on a worksheet including the files located within it's subfolders? I found a bit of code at [URL] that is as follows, but I can't seem to get it to read the files in the subfolders... Also, would it at all be possible to hotlink each entry so that the user can double-click the name in the sheet and open the file?

VB:

Sub ListAllFile() Dim objFSO As Object Dim objFolder As Object Dim objFile As Object Dim ws As Worksheet Set objFSO = CreateObject("Scripting.FileSystemObject") Set ws = Worksheets.Add 'Get the folder object associated with the directory Set objFolder = objFSO.GetFolder("C:") ws.Cells(1, 1).Value = "The files found in " & objFolder.Name & "are:" 'Loop through the Files collection For Each objFile In objFolder.Files ws.Cells(ws.UsedRange.Rows.Count + 1, 1).Value = objFile.Name Next 'Clean up! Set objFolder = Nothing Set objFile = Nothing Set objFSO = Nothing End Sub
