Automatically Wipe Free Space

Hi, I just joined the Members Forum about 5 minutes ago. I have a registered version of CCleaner Professional which I have been using for the last couple of months. I could be classed as a 'Newbie' with computers too.

Anyway, before joining the forum, I had read several comments in the forum regarding the Drive and Free Space Wiper which has resulted in a couple of questions that I would like answered please.

1) Why doesn't CCleaner automatically wipe the free space when a computer has been idle for at least an hour? Most people sleep for 5 to 8 hours each night, so why doesn't CCleaner wipe the free space automatically during these periods?

2) I am currently doing my first wipe of free space on my drive. When it was at 1% it said it had 34 minutes of time remaining. Now it is at 10% and has changed to 7 hours and 52 minutes remaining. When I download a movie off the internet, it tells me how long it will take before I start the process. Why can't CCleaner tell me at the start how long it will take to do the job?

3) Now supposing every night, I do one wipe of the hard drive on the free space setting. Will this process get quicker each night that I do it. For an example, at 10% now, I have 7 hours and 52 minutes remaining. So in 40 days time, will the 10% be down to say an hour?

Thank you

This has all been said before on the forums multiple times:

* Wipe Free Space ("WFS") isn't something you should be using regularly because it has the potential to wear out the hard disk causing it to fail.

* WFS is something you use when you want to sell off or donate your computer.

Okay thanks.
