How determine by which version of Grasshopper a .gh file was made?

I trying to open a particular .gh file, but when I open it, I get this message:

It seems I am using an old or new version of Grasshopper.

How can I identify by which version of Grasshopper was this .gh file made?

Thank you.

The easiest way is to use the Grasshopper File Viewer located in "C:\Program Files (x86)\Rhinoceros 4.0\Plug-ins\Grasshopper"

Is D: a memory stick?

Scratch that I can see it clearly isn't.

I think this normally occurs when the file hasn't finished writing to the storage device when it is interrupted. Most often by pulling a Memory stick out.

Yes. Here it is.
A couple of files can not be opened, not only this one.
