Cannot Save Warcraft III Campaign

Where is your Campaign progress saved

Classic and Reforged Campaign progress is saved separately. 

Campaign progress is saved locally in the Documents folder in your computer. If you want to play on a different computer, you can copy over your Campaign folder to the new computer to resume your game.

Can't save?

If you can't save your Campaign progress it may be that you don't have permissions to write on the Documents folder. If your Operative System is Windows: 

1. Check your Windows user has permissions to write on the Documents folder. Otherwise, try creating a new administrator account to resolve permissions issues.
2. Check if OneDrive is preventing Battle.net Games from accessing or modifying files in your Documents folder and unsync your Documents folder from OneDrive.
