Thanks for the explanation that the file went away on its own. I'd guessed  
as much, but confirmation is helpful.

No, that would be a Java-ism ON the Mac, with Mathematica doing nothing to  
remedy the situation... as it clearly could, or the second argument  
wouldn't be possible. Files created in Mathematica usually go into my  
/username or working directory, and I see no reason that shouldn't apply  
to FetchURL as well.

Wherever blame (or credit?) lies, I can safely say that not once, in 41  
years of computing, have I EVER wanted to create or download a file where  
I couldn't see it.
