I'm guessing here, but yes ... I think tilde was an unfortunate
choice.

Several programs create temporary files that begin with tilde,
and as such many cleanup utilities (perhaps even Windows own)
will *assume* that any file beginning with a tilde is a temporary
file that can be deleted.

I'd choose something else - perhaps something "a." or "0."
to be safe.
