How to Merge Map Progress in Profiles for ETS2 and ATS – 2026 Guide
New game versions updates are here so we will also see the mods updates and it is perfect time to make you perfect profile.
In this guide I explain how to merge several profiles map discovery progress on example of merging vanilla 100% and Promods 87% profiles on ETS2 1.58. You can try this scheme on future versions in both ETS2 and ATS. Below you can find link to text version, tools and also ready strings used in this video.

Guide:
1. Reason
There are several reasons. The most common one:
You play vanilla + DLC on one profile. And you play mod maps like Promods or Roextended on another profile.
Keeping them separate is fine. But what if you want:
- Your 100% vanilla discovery
- Plus your mod map exploration
- Combined into one master profile
Another reason:
You created a new profile for TruckersMP or testing purposes. And later you want your original progress back
Or maybe you lost progress after an update and want to rebuild quickly.
In all these cases — merging discovered map items makes sense.
Important:
In this tutorial we are merging only discovered map items.
We are not merging:
- Garages
- Money
- Drivers
- Trucks
- XP
That is a completely different topic.
2. What Was the Problem With the Old Method?
My year-old guide is still mostly actual and you can still use Notepad++ or other editor but new guide can save you hours. Let me remind you that in every profile, discovered roads are stored in a strict indexed order inside the game.sii file.
If you simply copy part of the data:
- The order becomes incorrect
- Duplicate entries appear
- The profile may crash
- Or the game may behave unpredictably
And this becomes a serious problem because:
- Vanilla profiles contain thousands of discovered entries
- With map mods, this can grow dramatically
Manually fixing that with Notepad++ used to require:
- Regex
- Manual renumbering
- Removing duplicates
- Reindexing everything from zero
It worked — but it was slow and error-prone. So today we go another way. We automate the process using a Python script.
3. Make backups!
If you plan to modify game files always Make backups! This is extremely important.
Your profiles are located by default in: Documents/ETS2/profiles or Documents/ATS/profiles
Copy the entire profiles folder somewhere safe. If something goes wrong, you restore everything in seconds.
Disable Steam Cloud synchronization for all profiles involved. We cannot modify profiles that are stored only in Steam Cloud. After disabling Steam Cloud, profiles will be saved locally in the Documents folder.
4. Preparations and tools
As always for manipulations with the profiles we need several tools:
Truck Tools for save decryption – it is free of charge application you need to install to make various actions with you profiles in both games. You can also use your preferrable tools for game files decryption

Sublime Text – we need good text editor that allow us to run big files. While I use Sublime, you can use your preferable text editor like Notepad++ or even VS Code.

Python installed on your system – it will run my script. Python is also free of charge.

The merge-discovered.py script – you can download the script for free

How to use Python?
1. Go to the official website: python.org
2. Download the latest stable version for Windows.
3. Run the installer.
⚠️ Very important: Before clicking “Install”, check the box: Add Python to PATH This is critical. If you skip this, the `python` command will not work in Command Prompt.
4. Click Install and wait.
5. That’s it.
How to Check If Python Is Installed?
Open Command Prompt and type: python –version or py –version
If you see something like: Python 3.x.x You’re ready to go.
If you see an error like “python is not recognized”, then:
Either Python is not installed
Or it was installed without adding to PATH. In that case, reinstall and check the PATH option.
Before starting
1. Make sure all profiles you plan to modify have Steam Cloud disabled.
2. If merging modded profiles, verify that all required mods are present in your mod folder.
3. Enable file decryption in config: g_save_format 2
4. Enable console: uset g_developer 1 and uset g_console 1
5. Make sure all profiles are from the same game version (don’t combine ATS profiles with ETS2 profiles and vice versa)
5. Prepare profiles
Enter each profile you want to merge.
Create a new save to identify them easily by timestamp.
Decrypt each profile using Truck Tools.
Inside each profile, locate the file: game.sii and copy them one by one to a new folder.
6. Merging Process
With the old method, you had to manually clean and reorder everything in Notepad++. With the new method, we only extract the necessary data in seconds.
Instead of manually:
Removing prefixes
Reordering numbers
Re-adding brackets
Generating incremental indices
Removing duplicates
We now use a Python script that:
Extracts all discovered item IDs
Removes duplicates automatically
Reorders them correctly
Recreates properly indexed discovered items entries
Outputs a ready-to-paste result
Shows you stats
Collect all game.sii files from desired profiles in one folder.
You can rename them as you wish, just make sure that they have .sii extension. Example profile3.sii or promods.sii etc.
Put the script merge_discovered.py to the same folder.
Open terminal or command prompt in the script folder (right click with Shift – Open Powershell window here) and type: python merge_discovered.py
or py merge_discovered.py
Press enter
The script will:
Detect all `.sii` files in the folder
Show how many items were found per file
Show total collected items
Show duplicates removed
Generate output file: merged_discovered.txt – fully indexed and ready to paste.
Then Open the target profile’s `game.sii (The profile in which we want to get results of merge)
Replace its `discovered_items` block with the newly generated one.
Save the file.
Open the save in the game.
Enjoy the results.
One known side effect
Recruitment agencies may not work properly after modifying discovered items. If you attempt to hire new drivers after merging, the game may crash.
Recommended workaround: Hire all drivers you need before modifying profiles.
