Scriptcase 8 "Backup" folder

What is the “Backup” folder in Scriptcase and how do I use whats in there?
I was looking around the folders in Scriptcase and found “Backup” and in there is the folder of my Project name… with subfolders, etc.
I have had to reload SC and lost my projects… but I see my most important project in the “Backup” folder… but how would I get the new install of SC 8 to recognize it?
Thanks for any help!

I think every time you make a backup is stored there. Not sure, I save my backups outside
