Servers.dat format

The servers.dat (file located in the .minecraft folder) is used to store the list of saved multiplayer servers. It does not store the direct connect IP address or any LAN server information. It is stored as an uncompressed NBT file. It is possible to add color codes by editing the server name attribute with an NBT Editor, using the section sign ( § ).
