URL 'file:' format

It seems it's dumb question week for me - many of you will wonder how
I've gone on with RR development for years and not known the answer
to this one... anyway:
I only work with local text files in my current app, and I've never
had to use the 'URL' form. However I think it would be convenient to
do an update of a file using this form, since I want to be able to
read the contents of a file and then replace the entire contents. The
'open for update' and 'write to file' commands don't seem to to make
this very convenient, but of course I may be misreading the docs...
so I decide to use the form:
get URL someFileDesignation
... do stuff to 'it'...
put it into URL someFileDesignation
which seems from the docs to be an OK thing to do.
Anyway I tried to create 'someFileDesignation' as
where everything after the "file:/" is a known valid file path (it's
Windows XP, but of course RR internal format) and this can be proved
by opening the file in text editor. I've tried putting 0, 1 and 2 '/'
characters after "file:" but I always get "can't open file". The docs
are not explicit on this point, and I've run out of guesses. What is
the format supposed to be? And should I open the file first (I assume
not, as this isn't mentioned in the docs).
Sorry if everyone else knows the answer, but there it is...
