Bethesda's popular shelter management simulator allows players to spend dozens of hours building the perfect infrastructure and protecting residents from radiation. However, a situation often arises when the progress achieved on a large monitor screen wants to be continued on the road on a mobile device. Unfortunately, the developers did not provide built-in cloud synchronization between the PC and Android platforms via a Bethesda or Steam account.
This means that the user will have to resort to manual file transfer. The process requires care as folder structures and file formats may vary. In this article, we'll look at proven methods that will help you avoid losing hundreds of hours of game time when changing devices.
First of all, you need to understand where exactly the game data is stored on both devices. Local files contain information about resources, residents, their characteristics and current events in the wasteland. Any mistake when copying or renaming can lead to the game on your phone not recognizing the save or, worse, launching it with errors.
Searching and preparing files on your computer
The first step is to search for the source data on your personal computer. The location of the files depends on which version of the game you are using: a licensed version from Steam, a version from the Microsoft Store, or a pirated build. In most cases, the standard path leads to the system documents folder.
If you play through Steam, then look for files along the path C:\Users\[UserName]\Documents\My Games\FalloutShelter. This is where the files with the extension .savthat we need are located. Their names usually look like SaveGame_X_X.sav, where X is the number of the save slot.
- 📂 Open Windows Explorer and go to the Documents folder.
- 🔍 Find the directory
My Games, and inside it -FalloutShelter. - 💾 Copy the necessary files
.savto a separate folder for convenience.
It is important to note that along with save files, sometimes you need to transfer configuration files if you want to save specific graphics or control settings, although the main progress is stored in files SaveGame. Make sure that you copy the files with the most recent modification dates so as not to roll back your progress.
⚠️ Attention: Before starting any manipulations, be sure to back up the original files on your PC. If the process doesn't go according to plan, you can easily restore the original state.
Preparing an Android device
On the mobile device side, the preparation process depends on the version of the operating system. On Android 10 and higher, access to system folders is limited by security policies Scoped Storage. You will need a file manager with advanced access rights, for example Total Commander or ZArchiver.
Initially, the save folder on Android may be missing if you have never launched the game after installation. Therefore, first of all, launch Fallout Shelter on your phone, create a new shelter and save. This action will create the necessary directory structure.
☑️ Preparing Android
The path to files on modern versions of Android often looks like this: Android/data/com.bethsoft.falloutshelter/files/. However, in some cases, especially on older versions of the OS or custom firmware, the path may lead to the root of the internal memory in the folder FalloutShelter. If you don't see the folder datacheck the storage root.
Data transfer methods
There are several ways to deliver files from your computer to your phone. The choice of method depends on the availability of cable, Internet speed and personal preferences of the user. The most reliable option is a direct connection via USB.
When connecting with a cable, select the file transfer mode (MTP) in the smartphone notifications. After this, the device will appear in “My Computer” as an external drive. You can simply drag previously prepared files .sav from a folder on your PC to the corresponding directory on Android.
| Transfer method | Speed | Reliability | Complexity |
|---|---|---|---|
| USB Cable | High | Maximum | Low |
| Cloud (Google Drive) | Medium | High | Medium |
| Wi-Fi Transfer (App) | Depends on the network | Medium | Low |
| Bluetooth | Low | Low | High |
If using a cable is not possible, you can use cloud storage. Upload your save files to Google Drive, Yandex.Disk or send them to yourself in Telegram (“Favorites”). Then download them to your phone and move them to the desired folder through the file manager.
Use an archiver (ZIP) when transferring files via instant messengers so that the Android system does not try to rename or change the .sav file extension when downloading.
Replacing files and renaming
Once the files are on the phone, the most critical stage is approaching. Save files from a PC often have names that don't match what the game created on Android when it was first launched. You need to replace the files manually.
Open the file manager on Android and go to the game save folder. Delete or rename old files (for example, adding a prefix _old) that were created automatically by the game. Then rename the files copied from the PC so that their names match the original file names of the Android version, or simply paste them, agreeing to replace if the names already match.
Often on a PC the files are named SaveGame_1_1.sav, but on the phone they may be SaveGame_1_0.sav. In this case, rename your PC file to the format expected by the game on a mobile device. Exact name matching is sometimes required for the game to see the save in the list.
⚠️ Attention: Make sure that the file extensions remain
.sav. Some file managers hide extensions by default, which can lead to a renaming error..sav.txt.
What to do if the game says “The file is damaged”?
This often happens when copying is incorrect. Try copying the file again. There may also be a problem with the game version: if the PC version is 1.14, and the phone version is 1.10, the save may not open. Update the application on Google Play.
Using emulators as an alternative
If directly replacing files seems too difficult or does not work due to differences in game versions, you can consider an alternative route. Many users prefer to run the Android version of the game directly on a PC through emulators, such as BlueStacks, NoxPlayer or LDPlayer.
In this case, you install the emulator, download inside it Fallout Shelter from Google Play and log in to your account. Since the emulator simulates an Android environment, you can use the emulator tools to import files from a Windows folder into the internal memory of the virtual device.
This method is often more stable, since it does not require manual renaming of files if you know how to correctly forward folder paths in the emulator settings. You simply copy the save file to the emulator folder, which it sees as Android's internal storage.
- 🖥️ Install the Android emulator on your PC.
- 📥 Download the game inside the emulator.
- 📂 Use the “File Forwarding” function (Shared Folder).
- 🔄 Move the save to the desired directory inside the emulator.
The main advantage of emulators is that they allow you to use mods and scripts to manage saves that are not available on a regular PC. However, the consumption of computer resources will be significantly higher than when running the native PC version.
Possible problems and their solutions
Even if you strictly follow the instructions, nuances may arise. The most common problem is version incompatibility. The game is constantly updated, and the structure of save files may change. If the PC has an old version and the phone has a new one (or vice versa), the game may refuse to load progress.
It is also worth considering the difference in architecture. The PC version may use a slightly different encryption algorithm or checksums for files .sav. In rare cases, it is necessary to use special converters that can be found in the modding community, although they are usually not needed for a basic transfer.
If after replacing the files the game starts but shows “New Game” instead of your refuge, check the folder permissions. On Android 11+, apps are prohibited from reading files from shared folders without specific permission. Try placing the file in Android/data/..., and not in the root.
The success of the transfer depends on the identity of the versions of the game on PC and Android. Always update the application to the latest version before copying files.
⚠️ Attention: File manager interfaces and paths to system folders may vary depending on the smartphone manufacturer (Samsung, Xiaomi, Pixel) and shell version. If you do not find the folder in the specified path, use the file search inside the manager.
FAQ: Frequently asked questions
Is it possible to transfer saves via the Steam cloud?
Unfortunately, no. Steam Cloud only syncs saves between computers. The mobile version of the game does not have integration with Steam Cloud for cross-platform progress.
Is it safe to use third-party apps for conversion?
Using unverified converters carries the risk of data loss or the introduction of malicious code. It is recommended to use only manual copying of files or time-tested tools from well-known modders.
What to do if villagers are missing after the transfer?
This may indicate damage to the save file when copying. Try restoring your backup. Also make sure that you have copied all files related to a specific save slot, if there are several of them.
Do you need root access to transfer?
On modern versions of Android (11, 12, 13, 14), access to the folder Android/data is possible without root access via the system's standard file manager or special access requests that appear when you try to enter this folder through third-party managers.
Will this method work for Fallout Shelter Online?
No. Fallout Shelter Online is a standalone, server-based game. Progress there is stored on the developer’s servers and linked to the account, so manual file transfer is impossible and unnecessary.
