There are many different files in Autorank's folder and might be somewhat frightening for new users. This page serves as a general overview of these files and to understand what they do. For more detailed info, go to the page that is dedicated to that file.
This file can be used to translate strings used by Autorank to your favorite language. By all means, adjust them in whatever way you see fit!
The data folder
Files in this folder store the play-time of all players, separated by time unit (daily, weekly, monthly and total time).
The backups folder
Autorank will automatically backup your data files periodically. The backups will be stored in this folder.
The uuids folder
Autorank will cache the UUIDs of players so that it doesn't need to make request to the Mojang server whenever a player name needs to converted to a UUID. Do not alter these files.
The logging folder
Autorank will log its actions to separate log files so you can investigate when something went wrong. Generally, you don't need to touch these. If the folder gets too large (in size), remove the oldest files.
