Yes, you're using the absolute path. I was just checking to see if you
might have been trying to create a file in a write-protected directory
or a place that didn't actually exist, which could have been a result
of using a relative path and having GRC point to a place you weren't
expecting.

But with this info, I'm not sure. That's not an error that GNU Radio
is producing; it's the OS. If you replace the file sink with something
else (like a null sink), do you get the same error? I'm just checking
here to see if it's a problem with the file you are trying to open or
maybe complaining about something else.
