The Contents of a Save

The Contents of a Save

This article is a draft. You can help Medieval Engineers Wiki by completing it. Click to edit this page

This guide is intended to give you some basic information about what is inside of your saves. This information can be useful for a lot of reasons: restoring backups, changing world settings, editing or deleting player information, or anything else you can think of. Some extreme examples include adding planets, adding or removing grids, and modifying grids and inventories. These extreme examples won't be covered here but the information provided should help with the more reasonable ones.

Location

Path to saves

All Medieval Engineers saved data can be found inside of the AppData folder. By default this path is C:\Users\{username}\AppData\Roaming\MedievalEngineers\. This path has a Windows shortcut of %appdata%\MedievalEngineers. This folder contains Blueprints, Maps, Mods, Saves, Screenshots, ShaderCache, Storage (used by mods), Workshop Worlds, Controls configuration (key bindings), Interface configuration (used by the general search screen for now), MedievalEngineers configuration, MedievalEngineers log, VRageRender-DirectX11 log. The Saves folder is of primary interest to this guide. Inside the Saves folder you will find numbered folders that correspond to each Steam account that has been used to play Medieval Engineers on your PC. Each sub-folder of these account folders is what we refer to as a save.

Folders and Files

Inside each save folder you will find the following:

Type	Name	Description
Folder	Backup	Contains backup saves. Each backup is a full copy of the save from an earlier state. These saves are identical in structure with the exception of not having their own backup folder.
Folder	Players	Contains .player files. These files have information that is specific to each player who has joined the world. They are named by Steam ID.
.vx2 File(s)	Voxel Modifications	This is generally one file, the planet, however the option exists to have multiple files if other bodies are added. vx2 files are compressed binary files that contain changes to the voxels. Planets are generated from maps in the game files specified by the scenario, modified by the scenario if needed, and then modified by the save.
.sbc File	Configuration	The configuration file contains all of the settings for the world such as those specified in world settings and advanced world settings. Also contained is version information, player identities (Steam ID to character ID mapping), and general session information.
.sbs	Save Data	This file contains all information about the save that is not in any of the other files. This contains all bot information, session components, Houses/ranks/deplomacy, banners, decay, fast travel cooldowns, farmables, access keys, areas, spawn information, and every entity (item, grid, character) in the world.
.jpg	Thumbnail	A screenshot that is generated when the world is saved. This is automatically scaled to reduce file size.

Players

Each of these files contains all information relevant to a single player in the world. Not all information generated by the player is saved in this file. What is included in the file is actually determined by the game architecture in that any entity component used by the character will serialize data to this file.
