LimeWire
LimeWire is just about the best file sharing program that I have ever come across with. And it is the fastest as well, especially when it comes to version 4.14 of the program itself! With LimeWire 4.14, I have better control over shared folders in my network. I also have a built-in Bittorrent Support system in the program! This means I have more ways to share files with my friends!
Another thing that I enjoy about LimeWire 4.14 is the fact that I receive notifications when my downloads are done already. And the same goes no matter what application I am currently using! This is just about the most convenient feature this new version can boast of!
