What does this have to do with Microsoft Access, the database application?
This newsgroup is for questions about creating databases in Microsoft
Access. If you repost to an appropriate newsgroup, I'd suggest turning off
your caps lock key and typing properly. It is much easier to read.
In an attempt to answer your question...
If he was viewing things that you have recently viewed, I'd guess he looked
at your "My Recent Documents" link in the Start menu, or looked at your
Internet Explorer history, or opened your picture viewing software and
looked at the recent file list in the File menu. Or maybe he just went to
your "My Pictures" folder. Or he did a search for all pictures on your hard
drive. Lots of possibilities.
Your post does not really make it clear why you are asking. Did you think
that someone using your computer would not be able to view files on your
computer? Did you think that your Internet history was not stored?
