I can try and help you but I don't work at Oxtord Games. What do you mean tho? The files are located in Appdata, to access those you need to do these simple steps: (Windows only)
1- Press Windows + R keys on your keyboard.
2- Type in the app that has opened (called "Run"), "%appdata%".
3-From there, a folder will open, find and open "MMFApplications".
In there you will find (probably other games too) OuroboroS, MsLemonS, MrTomatosV2 and Resolution v1, you don't want to change anything tho, it will reset your progress (I tried). If you need more help add me on discord Lino#5541.
