Temp directory is odd

Hello

I have a few questions about the "C:\Documents and
Settings\USERNAME\Local Settings\Temporary Internet Files",
directory..
I know whats there, and what its for, but this directory is not like
every other directories. It have filenames with "/" chars in it, I
cannot make these files manual, or are them some kinda virtual files?

I was also wondering what thoses content. directories is.. And why are
they superhidden? Example "Content.Outlook", I cannot see it while
browsing the temp folder, but I can access it manually..

Regards
  Lars
