Simple:
To copy save from PC to Switch:
1. Make sure you have at least one Witcher save on Switch
2. On the Switch make backup of your Witcher saves with Checkpoint app (remember to make backup of proper user's saves!)
3. Copy your PC save of your choice (PNG+SAV) to your sdcard into your switch...
