How to sync Fallout Shelter on PC and Android (Fallout Shelter)

What do we need?
First of all, we need two programs: Dropbox and Dropsync. Download Dropbox to your computer from this site: https://www.dropbox.com/install and to your phone from PlayMarket. Dropsync download only on the phone and also from Playmarket'a.
Synchronization.
First of all, you need to sign in to the same Dropbox account on your devices. For example, you log in to your Google account both from a PC and from a phone. I don't think it's worth explaining here.




Now, sign in to your Dropbox account in Dropsync on your phone. Here you can do it yourself.




Well, everything is ready to start all these dances with a tambourine. Let's start.

1. You need to make a folder in your Dropbox folder on your computer. To do this, click on the Dropbox icon in the lower right corner of the screen, then click on "Open DropBox Folder". Create a folder there called Fallout Shelter.









2. Go to Dropsync on your phone, skip the Sync Wizard, then in the "Folders" section, click on the "Choose what to sync" button. In the first empty field, enter the path to your Fallout Shelter file that you just created on your computer. You do not have to look for it, everything will be highlighted automatically. Click on the second empty field and type in the path: Android/data/com.bethsoft.falloutshelter/files
Press the confirmation button, if there is one, and make the slider blue on "Enable sync". Ready. You can check if the sync works. To do this, go to the Fallout Shelter Dropbox folder on your computer that you recently created. If the game files appeared there, then everything is working.




3. You need to delete the FalloutShelter folder in the Local folder. To do this, go to start, type in the line% AppData%, open it, then go to Local and delete the FalloutShelter folder. Yes, you will have to part with the saves on your computer.

4. The most tedious part. You need to make a symbolic link on your computer. Go to Start, type "Command Prompt". Right-click on the highlighted "shortcut" command line and select run as administrator. Note: For this you need an administrator account in your Windows. How to do it, you can find on the Internet.




5. After you have opened a command prompt as an administrator, you need to enter this command into it:

mklink /D "C:Users<your computer name>AppDataLocalFalloutShelter" "C:Users< your computer name>DropboxFallout Shelter".

ATTENTION: The slightest mistake in the team, and you will fail. Write exactly the same as mine. Respect all spaces and capital letters.

You can find out the computer name in the Start menu in the upper right corner under your avatar or
Left-click on Start, then on "Settings". See this screen. Click on "System. Screen, notifications, app, power. Further down, on the left, you need to click on "About the system".





6. Now go to the same folder where you deleted the FalloutShelter folder, that is, AppData - Local. If the same folder appeared in the file that you deleted, only with a small sign on the bottom left in the form of a shortcut, and the folder itself contains game files, then you have succeeded.








Conclusion.
To test if the sync is working, log into the game on your phone, make any changes, and exit the game completely. Then go to Dropsync, and there click on the button with two arrows in the upper right corner. Wait for the download and go to the game on the computer. If there are these changes, then your game is fully synchronized. Congratulations! Do exactly the same when you're done playing on your computer or phone. Nothing complicated.


When synchronized, hacking a game on a PC using Trainer or other third-party programs works on a mobile device as well. I launch the official game on the PC from Steam, use the Trainer and everything works. It has been working for me for quite a long time without any problems getting achievements both in Steam and in google play.
