How to Download Your Save Games From Steam Cloud. Steam synchronizes many save files to its servers. They’re automatically downloaded via Steam when you install a game, but that’s not the only way you can get them. You can download them directly from Valve’s website in your browser, too.
Enable Steam Cloud Sync in Steam
If Steam isn’t automatically downloading your old save games after you install a game, ensure Steam Cloud is enabled for that game within Steam.
To do so, locate the game in your Steam library, right-click it, and then select “Properties.” Click the “Updates” tab and ensure the “Enable Steam Cloud synchronization” option is checked for the game. If this option isn’t checked, Steam won’t automatically download your cloud saves—or upload any new ones.
If you don’t see a Steam Cloud option for a game here, that game doesn’t support Steam Cloud. Not all games on Steam do—it’s up to each game developer.
