Forza Horizon 4 Save File Location (Steam & MS Store)

1. Press Win + R
   
2. Copy and paste the following into “Run” window%localappdata%\Packages\Microsoft.SunriseBaseGame_8wekyb3d8bbwe\SystemAppData\wgs
3. Voila! You’re in the save file folder, and I wouldn’t recommend screwing over with save files without doing any backup.

The end result in explorer should look approximately as shown:

1. Press Win + R
   
2. Copy and paste the following into “Run” windowC:\Program Files (x86)\Steam\userdata\
   (In case if you didn’t change the default Steam installation folder)
   
3. Sort by “Date Modified”, and open the first recent folder (mine is “162934955”, because of AccountID number, which you can find yours on SteamDB[steamdb.info])
4. Open folder that reads “1293830” (FH4’s AppID number on Steam), and then open “remote” folder
5. Voila! You’re in the save file folder, and, no, you can’t move over MS Store saves to Steam, sadly (yet!) 🙁

The end result in explorer should look approximately as shown:

• Can you move over MS Store save files to Steam version FH4?
  —Unfortunately, but you can’t move over MS Store saves to Steam 🙁
• Can I somehow Jerry-rig MS Store saves into Steam version of FH4?
  —No, you can’t Jerry-rig, and instead you will be greeted with repeating “Invalid Profile” message until your game crashes it way out with error code “E:88-d”
  
• Do Steam saves work in MS Store version of the game?
  —This question remains unconfirmed, but I’d probably say no, because both versions store saves in a completely different way to the point that Steam version doesn’t recognize save from MS Store version of the game.
