What if I have a large file on the server that I want the wp library to have?

I did flag this question as a duplicate of this one: Is there any way to add images to the Media Library through a path on the server?.
Which points to the plugin Add to Server as the article linked by @RyanB in the comments…

But, wondering on the issue, a creative solution is uploading a bunch of dummy files with the same names of the big ones and replace them with the real ones inside the /uploads/ folder. This would only work with audio and video files as they don’t generate thumbnails nor metadata.
