That does make me feel a bit more confident. If all the obvious stuff is in there, presumably it's not also any other files.

Yeah, I knew that much already. But still when dealing with computer security such I'd rather be too careful than not careful enough. So I don't want the copy linked to me in any way. For instance, I could easily imagine that some of those files might have my personal spend transactions recorded in a different order since my client knows about them before anyone else. (No idea if that's actually true, but that's the kind of thing I'm wondering about.) I like the fact that Bitcoin is pseudonymous, and want to keep it that way.

I realize of course that if I seriously got in the habit of handing out copies of this stuff I could simply make a clean install and download the whole monster database again. This is mostly hypothetical (although I could see it happening) I just feel uncomfortable having this huge chunk of data and not knowing whether I should regard any of it as sensitive or not. It's like I've got my house key attached to a car tire plus a half dozen other bits and bobs that I don't completely understand the use of.
