My message was confusing.  I mean the path to the current directory
may be either relative or absolute, but not false (as it is on
Windows).

I'm not sure I understand what you mean.  The documentation says:

,----[procedure] (file-exists? STRING)
| Returns STRING if a file with the given pathname exists, or #f
| otherwise.
`----

Isn't (file-exists? ".\\") supposed to return ".\\" on windows?

Best wishes,
