eMule is one of the biggest and most reliable peer-to-peer file sharing clients around the world. Many developers contribute to the project, so the network gets more and more efficient with every new version. The new eMule 0.50a (7 April 2010) introduces a new algorithm to verify downloaded files. This improves download speed as it reduces the number of corrupt parts. It also works better in Windows 7 and improves the interface making it easier to use.
