How do I specify a path with libcurl for file uploads/downloads? or What's the correct way to specify

libcurl specify path problems, huh? Yeah, it’s a common gotcha.

You *can’t* just throw a path string at it. Gotta use `fopen()` first. Also, make sure you’re using binary modes (`"rb"`/`"wb"`) or you’ll get weird issues on Windows.

For path differences, libcurl doesn’t care much—it’s more about how your OS handles paths. Stick to `/` if you can, but `\\` works on Windows too.

If you’re lazy, `CURLOPT_URL` can handle file:// paths, but that’s a whole other rabbit hole.
