what is this thing?

[tom arnall <kloro2006@gmail.com>]

I did a download via a torrent file, with results I don't understand. 
Rtorrent created a directory and put some files in it, all in a 
seemingly normal manner. But the stuff turned out to be a fake, so I 
tried to remove it. The result was that the non-hidden files went 
away, but two hidden files remained. When I tried to remove them, 
nothing happened except the names of the files changed. How does this 
happen? 

Thanks,
