Missing Files for Blank

Once is happenstance.
Twice is coincidence.
Three times is…

I have searched the forum.
No one has been asking for help with a missing file named “blank” until about two weeks ago.

Now there are at least three such cases.

(There was a fourth that I suspect is the same, four days ago, but the question “was it named blank” was never answered.
A fifth suspected case was eliminated; the file had a different name.)
