I also just lost all my tabs! I did not have an export anywhere. I have been using Windows 10 File History. But it looks like File History does NOT save the AppData folder!

However, I do have a recent system image of my entire laptop. Surely the SideWise data is there. Can you tell me where I would find the sidewise tabs data store? I would like to avoid restoring my entire laptop just to get at those stored tabs. Is there a way?
