Today I'll show you the easiest way to export profiles for SteelSeries Engine.
The method discovered by me because the internet are not very detailed.
Profiles on headphones, mouse and keyboard can save them now.
I hope it will be helpful

1) Exit Steelseries Engine
2) Show "hidden folders"
3) Go to C:\ProgramData\SteelSeries\SteelSeries Engine 3
4) Backup windowProps.json file
5) Enter in db folder and backup database.db-wal file

Thats all.
