Snapshots are not separate Binder entries. They’ll be associated with whatever document you actually snapshot-ed. So that’s probably not a concern.
Here’s what I would do:
- Use the File → Backup → Backup To command to make a backup of the entire project to a safe location.
- Create a brand new project with a unique name, and drag whatever you believe to be the current version (Duped Post Dev Edit?) into it. Close this new project.
(These two steps are to protect you in case something goes wrong.) - Back in the original project, create a new top-level folder with a name like “Old Versions.”
- Create another new top-level folder with a name like “Check Status.”
- The Duped DE Edit folder has the special icon indicating it is Scrivener’s “Draft” folder. Is this the version you believe to be current? If so, rename it to Draft, reflecting its status. If not, create a new folder and drag the entire contents – but not the folder itself – into it, then rename the folder to “Draft.”
- Enable the Outline view with the Created Date, Modified Date, and Include in Compile columns enabled.
- Starting at the top, look through every folder in the original project in Outline view. The idea is to move things that are definitely old to “Old Versions,” things that are definitely current to “Draft,” and things you aren’t sure about to “Check Status.” Ideally, you’ll find that the versions are more or less coherent – everything in “Novel Format” is old, for instance – but you should check every single file, just in case.
