What is a PROPERTIES file?

A PROPERTIES file is a settings file used by Minecraft, a sandbox block construction game. It is saved in plain text and stores configuration information for the game. PROPERTIES files may be used for configuring a Minecraft multiplayer server or a game mod.

More Information

The most common Minecraft properties file is server.properties, which stores configuration data for a multiplayer server. It saves information such as the level name, monster spawning settings, the maximum allowed players, and the server port and IP address.

You will most likely only come across the PROPERTIES file if you want to modify the configuration of a multiplayer server. After editing the file, you must restart the server in order for the changes to be applied.
