unlocking files

[T5]

I am trying to defrag my hard drive but it says that it is 40% fragmented
but I cannot defragment these files because they are locked.......... how do
I unlock them?

You don't. They are protected system files, and probably OS installation
files too. If you like to tidy up your hard drive, you should consider
deleting some old system restore points instead.
