I probably have to reinstall my computer, and I really don't want my savefiles to dissappear having to replay the game to play theupcoming DLC. Does gog galaxy use any kind of cloud save or does anyone know where to find the files manually to save on a usb and manually put it i to the game files when I reinstalled the computer?

Thank you in advance!

Galaxy does NOT have any cloud storage for saves (at least not yet), so be sure to manually backup your saves. They should be in Documents\The Witcher 3\gamesaves

Thank you for your response! So the file called gamesaves would be the only thing I would need? Thank you for your response! So the file called gamesaves would be the only thing I would need?

Yes, all saves are in the "gamesaves" folder.

You could copy the whole "The Witcher 3" folder from Documents, but aside from saves, the only other things there are setting files (audio, graphics, controls etc).
