Thank you for the reply MaryGrace.  I am not int he office now so I cant try what you said until later.  

But I am curious because the Attachment library file is called "Attachments Library.qbattach".  When I double click on it in my MAC, it asks which app I want to use to open it.  It's not a directory.  Isn't that the reason why I cant find the PDF attachment files in iCloud?
