I have a question that's probably not asked too often, because it has little negative impact on the user. I can't find it on The Google anyway.
So this question is for the edification of the curious-minded.
In my production environment I manually backup often. I have noticed that when simply duplicating files, they don't take up as much space as they used to in older versions of MacOSX.
As an experiment (because I am a nerd) I attempted to fill my hard drive by copying large files. Duplicating files barely changed the "capacity" / "available" numbers at all.
The duplicates are there.
Can someone explain this aspect of the OSX filing system to me? It's absolutely amazing!
