To answer your question, you are creating a string doing the for loop: ForEachObject{$_.FullName}

Have you looked at using HTML reporting? Don Jones put together a free e-book on it and there are various other articles on Powershell HTML reporting. Basically:

• Update .IsBodyHTML to $true
• Update .Body to ($empty_dir |ConvertTo-Html | Out-String)
