StrongDC++ is an improved version of DC++ to improve download speed management for all major P2P networks.
The good thing is that this program requires no installation. Simply decompress the file and run the program and you're off. The next step is to select the hub that you want to connect to. The hub looks very much like DC++ but with some important improvements. For example, you can now download from simultaneous multiple users without corrupting the file, it can distribute the parts of files that are not completed and can assign the download speed according to the sources available and the dozens of possibilities in customization of the interface. The improvement of the simultaneous downloading makes a significant improvement to download times and it's much safer than normal single source downloading. The developers point out that segment position and size are decided by file size and chunks speed. You can also set sounds, change the colour scheme or icons, show popup balloons, see emoticons and much more.
A sophisticated P2P application although it's a shame there aren't more users as you won't get many hits on the files you're looking for.
