Does "opening a file" mean loading it completely into memory?

There's an AudioFileOpenURL function which opens an file. With AudioFileReadPackets that file is accessed to read packets. But one thing that stucks in my brain is: Does AudioFileOpenURL actually load the whole monster into memory? Or is that a lightweight operation?

So is it possible to read data from a file, only a specific portion, without having the whole terabytes of stuff in memory?
