How do I gain access to compressed old files?
Just as you would any other files. They can be identified by their blue
color. They will automatically be uncompressed when you access them.
They are not "within" Windows Cleanup. Windows Cleanup is a program, not a
place. They can be anywhere on your drive.
And can I
permanantly delete them without causing any harm to the running of my
pc?
Sure. It's no different than with any other file, and depends on what they
are. If an old file is a photograph of your ex-wife that you no longer want
to look at, feel free to delete it. If the old file is your résumé that you
haven't used since you last looked for a job, you may want to keep it for
next time.
