Opening Old Projects Suddenly Broken

I am trying to open a set of projects that predate 2018.

In each case (in multiple projects, all from the same time period) it tells me that there were documents in the project that weren’t listed, and that files were recovered. It lists incomplete mobile syncing and permissions issues as potential causes. (Full error at the bottom.)

These files are the entirety of the former contents of the project. While the file structure is preserved separately-custom icons, nested documents and folders, etc-all of them are blank.

So I have the contents of the project in one long list with names like “rawenc-46”, I have no idea where in the project they were, and as some of these projects will have many files, it’s impossible to reconstruct.

This is a new error, as a few months ago I opened a few of these projects and had no problems doing so.

Any help you could give me would be deeply appreciated.

Full error message: (Again, neither of these apply.)

While the project was opening, files were detected within the project package that do not exist in the binder. This may have been caused by a permissions conflict, in which the file system refused the deletion of files from inside the .scriv package that had been deleted from the project binder, or by synchronization between different versions of the project (e.g. on a cloud service).

The recovered files can be found in the “Recovered Files” folder at the bottom of the binder.

Are you using any cloud service? If so, has the service been told to keep files downloaded?

They are in my Documents folder that is on my HDD but also on iCloud, but are fully downloaded right now.

I did have to download them before I could open them, though.

Did the upload to iCloud break them? If so, is there anything I can do to recover?

Assuming this is a permissions problem, which is entirely plausible as I’ve moved between three computers since the last time I opened these files, is there some technical fix?

How exactly did you move them?

Yes, permissions can be fixed via Finder. I’m more inclined to suspect incomplete synchronization, though.
