StrongDC++ is a powerful client for sharing files in Direct Connect network by using NMDC and ADC protocols. It is a modification of an original DC++ client and it brings many new features. Sadly, last release was a while ago, but it's still a very good client to share some files. Right after installation you would need to type your name and select folders to share and you are good to go.

You start sharing segments you've downloaded right away. So as other users. Better speed for everyone.
You have lots of options to fine-tune: sound notifications, popup windows, smilies, etc.
It frees slots for high-speed exchange.
Control your network and hard drive utilization.
