Can Horizon restore xbox 360 save files from a laptop?

Saved files to laptop before USB broke- won’t be used for modding, just want the files to work on the xbox again.

They’re saved under a “Content” folder moved from the 360.

Yes. You need to drag the saves into Horizon and then save them to your USB drive. If you’re going to be using them on a different profile you’ll need to change the profile ID and resign them before saving them to your USB drive.
