How can I cancel Steam's cloud sync?

Solution 1:

I found those instructions to disable Borderlands 2 (I don't know if Factorio) from synchronizing save data with Steam Cloud here:

• In your Steam Library, right-click on Borderlands 2 and select "Properties."
• Click the "Updates" tab.
• Uncheck "Enable Steam Cloud synchronization for Borderlands 2."
• Click "Close."

I imagine you already tried that, but it's all I found. If there's no other solution that's a pain in the ass, I assume save time will get even longer as your map keeps expanding, so I guess Steam will fix that for you if you ask, since it's their fault you can't really enjoy such a great game.

Good luck!
