Cool, was your project one of the ones mentioned on

Yes, it was!

I will pay very close attention to this and it was mentioned in both

 Thanks for that comment and even more information on the wiki about it

Thank you for the idea. Since, I do not know what kind of performance impact
it will have, it is nice to know of other methods that have different

I agree with both of you that it should not do that automatically. Ken has a
good reason why you might want to do it which is why I asked. It seems
conceptually reasonable that you might want to erase all traces of a file.
Of course, if it came to be that extreme, might as well completely erase all
the hard drives.

This currently is way above my head but it is one big problem that I do have
to solve as well. I am sure I'll have more insight once I take cares of all
these other questions going around in my mind.

Good luck!

To you too!
