I have a small home network which consists of my desktop and laptop. Its a basic one where my desktop is connected with a router and my laptop has a wifi card.

I have set up the shared documents so that I can put files in so both computers can see them but there is a problem; both computers have to be switched on to put a file in the other.

I want to know whether:

• Is there a way where I can put files into the desktop/laptop when one or the other is switched off?
  
• If not, is there some sort of synchronization system where I can 'drop' files somewhere and it will automatically send when both devices are switched on?
  
• Or is there any other feasible way to do it that I have just not thought of?

Any help is appreciated, thank you .
