What file types are disallowed to upload to wordpress webpages

Hello, I am running a Wordpress droplet using DO.

I am using Wordpress’ Browser Dashboard to manage my site.

I want to upload an executable file to the page however I am unable to because when I try this it returns an “unacceptable file type” error message.

Can you direct me to the acceptable file types to upload to my droplet?

Thanks.

For reference here is the go-by from Wordpress on how to Upload files.
