You can use the [ingest attachment plugin](https://www.elastic.co/guide/en/elasticsearch/plugins/current/ingest-attachment.html).

There an example here: [https://www.elastic.co/guide/en/elasticsearch/plugins/current/using-ingest-attachment.html](https://www.elastic.co/guide/en/elasticsearch/plugins/current/using-ingest-attachment.html)

```auto
PUT _ingest/pipeline/attachment
{
  "description" : "Extract attachment information",
  "processors" : [
    {
      "attachment" : {
        "field" : "data"
      }
    }
  ]
}
PUT my_index/_doc/my_id?pipeline=attachment
{
  "data": "e1xydGYxXGFuc2kNCkxvcmVtIGlwc3VtIGRvbG9yIHNpdCBhbWV0DQpccGFyIH0="
}
GET my_index/_doc/my_id

```

The `data` field is basically the BASE64 representation of your binary file.

You can use [FSCrawler](https://fscrawler.readthedocs.io). There's [a tutorial](https://fscrawler.readthedocs.io/en/latest/user/tutorial.html) to help you getting started.
