The goal is to easily exchange a large amount of data in a local area network environment like a LAN-Party. After you launched D-LAN, you will see all other people and their sharing automatically without special configuration This tool is by far the most easy LAN file share program. But it still requires file hashing (background task that will use 1 cpu and will take a while depending on your share sizes)

Advantages
easy to use, small program, background hashing etc

Disadvantage
hashing takes a while
