I have a simple question - I'm an AWS noob.

I've picked up a existing project (from previous developers) that uses AWS S3 as it's file host and media is contained in folders organized like:

......//picture.jpg

......//video.mp4

also, there is also a ......//manifest.json that just has this value:

{
    picture: "picture.jpg",
    video: "video.mp4"
}

There is only code to create this manifest file, but never fetched or used anywhere else, so I'm not sure if there's an underlying purpose with AWS to be there.

Is this file necessary?

If I continue to process uploads, but exclude this manifest.json, will anything break?

I've found this related article to manifest files, however the formatting is different and this project doesn't use quicksight so I'm not sure of its purpose here.
