A. The close button at the top-right side of screen only minimizes the Deepnet Explorer screen, so that Deepnet can complete transfer of your shared or downloaded files. If you exit Deepnet explorer, it disconnects from the P2P network and will not be able to complete file transfer. If you decide you want to exit Deepnet completely just select File > Exit from the system menu, or right-click on the Deepnet Explorer icon in the system tray and select Exit.
