Hi, Yma.
Who or what is Pit Stop? How do you know those files are "junk"? I'm not
saying they are not junk, but I'd like to know why you - or Pit Stop -
think that they are junk. If Pit Stop is a computer repair shop, why did
they not get rid of the "junk" for you?
The "how in the name of heaven" depends on what kinds of files they are -
and you've given us no clue about that. If you "can't even find them", it
will be hard for us to help you get rid of them.
Of course, you could get rid of them by reformatting your hard drive and
starting over, but that's drastic and would get rid of all your files,
including those that are not junk. :>(
We'll be glad to help you as soon as you give us enough information so that
we can help. Until then, we're just shooting in the dark.
