How do I know if I have open source vs basic

Elastic Stack Elasticsearch
1

So I downloaded elasticsearch (clicked on the download for opensource/basic), and I am wondering which one I have. The download button is the same for both, and there are features that basic has that open source doesnt.

Thanks in advance!

OSS from https://www.elastic.co/downloads/elasticsearch-oss
Otherwise: https://www.elastic.co/downloads/elasticsearch

is there any way to find out which version if I already downloaded it? This was a few months ago and Ive already done some work with it.

Also, did OSS vs Basic only start in versions 6.X.X?

I have two versions right now on two different applications, one is 6.X.X and one is 5.X.X

If you run

_cat/plugins?v

I can tell
