Lost 5 years in update -- pull from help folder?

I found a recent version in a back-up folder I’d hidden on my computer! The folder is called “[novel title] help.scriv,” and inside there’s a Files > Docs folder with all the little pieces of the different chapters and notes in different Word docs. Is there a way I can restore this version in the new Scrivener, or do I have to paste the text in section by section/doc by doc?

Original post:
Suddenly it seems to have replaced all versions of my novel AND backups with some version it somehow randomly found from 2015. HELP!!! I am freaking out.

Don’t mess with the Docs folder unless absolutely necessary.

Open the old project in the usual way, by double-clicking the .scrivx (Binder index) file or with File/Open in Scrivener.
