To use a save editor for Easy Save 3 (ES3) , you typically follow a process of locating the encrypted save file, decrypting it via a specialized tool, modifying the data, and then re-encrypting it for the game to recognize How the ES3 Save Editing Process Works Locate the Save File : Most Unity games using Easy Save 3 store data in the Application.persistentDataPath Common Path C:\Users\[Username]\AppData\LocalLow\[Company]\[GameName]\ File Extension : Look for files ending in Decrypt the Data
: ES3 files are often encrypted using AES. You cannot edit these directly with a standard text editor unless encryption was disabled by the developer. Online Tool : You can use specialized web-based editors like the Easy Save 3 Save File Editor to upload your Encryption Key
: You will often need the game's specific encryption password to decrypt the file. If you don't know it, you may have to find it through community forums or by inspecting game code. Edit Values
: Once decrypted, the data usually appears as a structured list of keys and values (similar to a dictionary or JSON). Search for specific keys like AmountGold to change their corresponding values.
: Some games use additional security, such as XOR operations on values, meaning you must calculate a "hidden value" using a key before editing. Save and Re-encrypt
: After making changes, use the editor to re-encrypt the file. Download the new es3 save editor work
Replace the original file in the game's save folder (always keep a backup of the original). Unity Discussions For Developers: Using the Built-in Editor Tools If you are the developer using the Easy Save 3
asset in Unity, you have access to built-in tools to manage save data during development: Easy Save - The Complete Save Game & Data Serializer Asset
Since "ES3" most commonly refers to The Elder Scrolls III: Morrowind in the modding community, I have designed a feature overview based on a modern, hypothetical save editor tool for that game.
However, if "ES3" refers to Easy Save 3 (the Unity asset for game developers), I have included a brief section at the bottom for that context.
Here is a feature profile for a Morrowind Save Editor. To use a save editor for Easy Save
Target Audience: Modders, power gamers, and players recovering corrupted saves. Platform: Windows (Standalone Executable)
If encrypted, the editor must either:
Gzip compression, if enabled, is then reversed using standard decompression libraries.
Some developers compress the ES3 data using GZip or Deflate before encrypting it. If you open the file and see a .gz header, a basic editor will crash. A working editor must decompress, decode, edit, re-compress, and re-encrypt.
Modern Unity games often add a "checksum" (a hidden math equation) inside the save file. If you change the health, the checksum fails. The game then deletes your "corrupted" save. A sophisticated ES3 save editor will recalculate and fix the checksum automatically. If it doesn't, the save will appear to work but then vanish on load. Feature Profile: The "ES3 Save Architect" Target Audience:
Consider a save file containing:
playerGold | System.Int32 | 150
playerPos | UnityEngine.Vector3 | (1.0, 2.0, 3.0)
A basic editor in Python might:
More robust editors (e.g., using the actual ES3 DLL in a standalone tool) can reuse Unity’s serialization logic to avoid bugs.
In modern game development, data persistence is essential. Unity’s Easy Save 3 has become a go-to solution due to its cross-platform compatibility and flexibility. However, from a user’s perspective, save files often act as a black box. ES3 save editor work refers to the process of inspecting, decoding, modifying, and re-encoding these save files to alter game state—such as changing currency, unlocking items, or bypassing progression locks.
This paper does not endorse cheating in multiplayer games but rather explores the technical feasibility and methodology for legitimate uses such as bug testing, accessibility modding, or personal data recovery.
