is there a program to open/extract .scriv files?

New at Scrivener.
Lost work.
Windows 7 cannot open the .scriv
I also tried Jzip and it cannot open the scriv files/folder.

Is there another program I can install to open these files.
I cannot open anything in the auto back up as the files are not recognized.

Also, there are duplicate folders in the open ‘recent projects’.

And, how can I get rid of the drafts in the binder that are duplicate and empty. I can’t get them to
go into the trash.

Please help.
Thank you
