Question about Outlook Express

Hello;

I just sent an email through my Hotmail Outlook account. I sent an attachment with it. I also saved a copy of the email to my "sent" folder. When I viewed the email in my sent folder to see how my attachment would be viewed it looks as if it sent all of my document folders and not just the attachment I intended to send...is it possible? Is it possible that the recipients of my email will now have access to all of my documents on my computer and not just the attachment I sent? Thanks.
