hey, why is the blockchain file generated in the parent folder of the folder the client itself is in? 
It's obfuscation/minimization problem. 
ah, thanks for the explanation, 
btw, is it possible to run several clients on the same blockchain, i'm running all my clients that are forging of different blockchains now, this is not a problem as long as the blockchain is about 10 mb, but will maybe become a problem later on.
