Steps

WARNING: You should manually back up your save files before proceeding with this guide. If you incorrectly perform the steps, you risk losing them!

NOTE: I am using Linux Mint for my guides, but the steps should translate pretty easily to your distro. I hope that if you are running Linux you know the basic operations. Steam Deck users should follow the guide specific to that platform.

Downloading and Installing Syncthing

1. Download Syncthing Tray from the Flatpak store.

2. Launch Syncthing Tray to run it, select the Start guided setup on the splash screen that appears and press Next.

3. It will then look for an existing Syncthing instance to pull settings from, but will likely fail to do so if you are here. Regardless, select the Yes, continue configuration option.

4. Select Start installed Syncthing application via Syncthing Tray, this means it will use a built in Syncthing executable rather than relying on an externally provided one. Press Next to continue.

5. You will now be presented with a confirmation window with your selections, confirm they are what you want and hit Apply to continue.

6. You will now be prompted with a confirmation window that has a QR code and the devices identifier - you will need one of these to add other devices to the sync system.

7. Syncthing/Syncthing Tray are now installed. Press Finish to close the pop up.

   NOTE: By default due to flatpak sandboxing limitations, Syncthing Tray will not run automatically on login. You can get around this by following the instructions here.

Configuring this Machine as a Parent

Use this when you want to set this machine as the initial source of truth (push files out to all the other devices). Afterwards they will all be equal partners, not a parent/child relationship, this just helps with initial setup.

1. Right-Click the Syncthing Tray icon in your taskbar and select Open Syncthing.

   1. If you don’t have a taskbar in your distro, you can also reach it directly by opening a web browser to: http://127.0.0.1:8384/.

2. You will now have a browser window open up to a web GUI to configure Syncthing. You will get a pop up about allowing anonymous usage and setting a password, make your selections to close them.

3. We’ll start by adding the folder with our save files that we want to sync by Pressing + Add Folder.

4. A pop-up window will appear, fill in the Folder label field with whatever you want to call it, like Switch Saves.

5. Enter the Full folder path to where your save files are stored on this machine.

   TIP: The easiest way to do this would be to open Eden, right-click a game that has a save, hit Open Save Data Location, and then go up 1 directory. It should contain folders with the TitleID of your games.

   It should look similar to this: ..\nand\user\save\0000000000000000\EC573727F509799675F6E5112C581D7E

6. Ignore the other tabs for now and hit Save.

7. The folder is now ready to be shared with other devices.

Configuring this Machine as a Child

Use this when you want to set this machine up as a child (pull files from the other devices). Afterwards they will all be equal partners, not a parent/child relationship, this just helps with initial setup.

1. Install Syncthing Tray on the client device following the section above. Copy the child’s ID and store it so it is accessible to the Parent.

2. ON THE PARENT: Right-Click the Syncthing Tray icon in your taskbar and select Open Syncthing if it is not open already**.**

3. You will now have a browser window open up to a web GUI to configure Syncthing. You will get a pop up about allowing anonymous usage and setting a password, make your selections to close them.

4. Navigate down to + Add Remote Device, we are going to add our Child device, so I hope you have its ID handy. If not, go back and get it.

5. Add the ID and Name the device, the device may appear as a nearby device, in which case you can just click it to pre-populate the Device ID.

6. Click the Sharing Tab, and check the box next to the folder you set up on the Parent (Switch Saves in my case). Hit Save.

7. We are done with the parent, now SWITCH OVER TO THE CHILD.

8. ON THE CHILD: Right-Click the Syncthing Tray icon in your taskbar and select Open Syncthing if it is not open already.

9. You should now see a connection request pop-up from the parent. Hit + Add Device to add the device.

10. Hit Save to finish adding the device.

11. That pop-up will close and you will get notification that the device wants to share a folder now. Hit Add.

12. Enter the path to the save folder in Eden and hit Save.

    TIP: The easiest way to do this would be to open Eden, right-click a game that has a save, hit Open Save Data Location, and then go up 1 directory. It should contain folders with the TitleID of your games.

    It should look similar to this: ..\nand\user\save\0000000000000000\EC573727F509799675F6E5112C581D7E

13. Syncthing will now pull all the files from the Parent and store them in your local save directory. At this point the files are in sync and alterations to one will affect the other and both can be considered “Parents” for other devices you want to add. Repeat these steps for as many devices you want.
